I am attempting to have phpexcel set the range for $objValidation based off a variable so not to have null values in my dropdown. This was my code
$objValidation->setFormula1('Index!$A$5:$A'.'count(Index!$A$5:$A$200');
which resulted in additional blank/null values in my dropbox making it bigger than need be. what I would like to do is something like this
$sql_temp = "SELECT `tempID`,`serialNUM` FROM `temp_sensor_specs` WHERE `statusTYPE`='SPARE'";
$result_temp = mysqli_query($link, $sql_temp);
$row_temp = mysqli_fetch_all($result_temp,MYSQLI_NUM);
$objPHPExcel->getActiveSheet()->fromArray($row_temp,null,'A5');
$count_temp = count($row_temp) + 4;
$objValidation = $objPHPExcel->getActiveSheet()->getCell('B4')->getDataValidation();
$objValidation->setType(PHPExcel_Cell_DataValidation::TYPE_LIST);
$objValidation->setErrorStyle(PHPExcel_Cell_DataValidation::STYLE_INFORMATION);
$objValidation->setAllowBlank(true);
$objValidation->setShowDropDown(true);
$objValidation->setErrorTitle('Input error');
$objValidation->setError('Value is not in list');
$objValidation->setFormula1('Index!$A$5:$A$count_temp');
So that didn't work I've also tried it in several variations as such
$objValidation->setFormula1('Index!$A$5:$A'.'$count_temp');
$objValidation->setFormula1('Index!$A$5:$A'.count($row_temp) + 4);
$objValidation->setFormula1('Index!$A$5:$A'$count_temp);
I really feel I've used syntax incorrectly, but can't figure out how. I've done similar range setting in loops for( $i=4; $i<=15; $i++ ){
$objValidation = $objPHPExcel->getActiveSheet()->getCell('B'.$i)->getDataValidation(); but also don't think this needs to be looped it should be a simple count and set that value as the count return +4 (as my dropdown starts on cell row 5)
thanks in advance
So the proper syntax ended up being `$objValidation->setFormula1('Index!$A$5:$A'."$count_temp");

I have generated an Excel table using PHPSpreadsheet including the style and the autofilter:
The problem is when I sort the data by the second and third columns, the table formatting is gone. This is how it looks like compared if I use Table Style directly from Excel (using Home-> Format as Table):
Is there any way to keep the formatting when I sort the table generated from PHPSpreadsheet?
Relevant PHP Code:
for ($rowNumber = 0, $rowNumberMax = sizeof($rows); $rowNumber < $rowNumberMax; $rowNumber++) //rows (all data)
{
$columnNumber = 0; //1 = A
for ($i = 0, $j = sizeof($tableColumns); $i < $j; $i++) //loop through table header label
{
foreach ($rows[$rowNumber] as $rowKey => $rowValue) //loop through single row data
{
if($tableColumns[$i] == $rowKey)
{
$sheet->setCellValueByColumnAndRow($columnNumber + 1, ($rowNumber + 5), $rowValue);
$currentCell = Utilities::num2alpha($columnNumber) .''. ($rowNumber + 5);
$sheet->getStyle($currentCell)->getNumberFormat()->setFormatCode('#');
$sheet->getStyle($currentCell)->getAlignment()->setVertical(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_LEFT);
if(($rowNumber+5) % 2 == 0)
{
//even row
$sheet->getStyle($currentCell)->getFill()->setFillType(\PhpOffice\PhpSpreadsheet\Style\Fill::FILL_SOLID)->getStartColor()->setARGB('ffd9e1f2');
}
else
{
//odd row
}
$columnNumber++;
break;
}
}
}
}
//set autofilter
$headerFirstCellPosition = 'A4';
$tableLastCellPosition = Utilities::num2alpha(sizeof($tableColumns) - 1) . '' . (sizeof($rows) + 4);
$sheet->setAutoFilter($headerFirstCellPosition . ':' . $tableLastCellPosition);
The problem is you were just applying formatting to the cells based on if the row was even or odd, but it wasn't actually replicating a table in Excel. You would find the same result in Excel if you just formatted every other row like you did with your PHP code, where the "table" format would get lost.
Somebody just recently implemented a first pass of the actual table feature in Excel: https://github.com/PHPOffice/PhpSpreadsheet/pull/2671
You need to be on PHPSpreadSheet version 1.23.0 in order to be able to use this.
Using that, you would have to modify your code but you can go to the Samples section in the code area and view how to implement it: https://github.com/PHPOffice/PhpSpreadsheet/tree/master/samples/Table
https://github.com/PHPOffice/PhpSpreadsheet/blob/master/samples/Table/01_Table.php
Here is the relevant code (I removed some of the lines and added additional comments from the 01_Table.php sample at the link provided).
Table styles can be found here: https://github.com/PHPOffice/PhpSpreadsheet/blob/master/src/PhpSpreadsheet/Worksheet/Table/TableStyle.php
// Create Table
$table = new Table('A1:D17', 'Sales_Data');
// Create Table Style
$tableStyle = new TableStyle();
// this line is the style type you want, you can verify this in Excel by clicking the "Format as Table" button and then hovering over the style you like to get the name
$tableStyle->setTheme(TableStyle::TABLE_STYLE_MEDIUM2);
// this gives you the alternate row color; I suggest to use either this or columnStripes as both together do not look good
$tableStyle->setShowRowStripes(true);
// similar to the alternate row color but does it for columns; I suggest to use either this or rowStripes as both together do not look good; I personally set to false and only used the rowStripes
$tableStyle->setShowColumnStripes(true);
// this will bold everything in the first column; I personally set to false
$tableStyle->setShowFirstColumn(true);
// this will bold everything in the last column; I personally set to false
$tableStyle->setShowLastColumn(true);
$table->setStyle($tableStyle);
Also make sure that you include the following to be able to use these:
use PhpOffice\PhpSpreadsheet\Worksheet\Table;
use PhpOffice\PhpSpreadsheet\Worksheet\Table\TableStyle;
Implementing that into your code will then allow you to sort using the auto filters and keep the formatting like you are expecting.
There are a few caveats such as:
Note that PreCalculateFormulas needs to be disabled when saving spreadsheets containing tables with formulae (totals or column formulae).
Also, as I am actually currently working on doing this, it doesn't look like you can apply an autofilter and have a table at the same time at this point.
That does appear to be on the todo list though, as the first link I provided the contributor has "Filter expressions similar to AutoFilter."
Otherwise, that should get you what you want and aside from being able to auto filter prior to creating the Excel file, it has worked well in my small testing.
Edit to add:
I think you can actually simplify your code a bit by using the functionality of PHPSpreadsheet to create a a spreadsheet from an array.
Documentation from PHPSpreadsheet can be found here: https://phpspreadsheet.readthedocs.io/en/latest/topics/accessing-cells/#setting-a-range-of-cells-from-an-array
You'll need to change it so that the array that is holding the info starts with your headers, so I believe that would look similar to this for your code:
$rows = [
['header1', 'header2', 'header3', 'header4']
];
Then you can populate the $rows array with your data from the rows either with a loop or just a single declaration depending on what you are putting in there, but basically using the below to populate the array.
$rows[] = [
$field1Data,
$field2Data,
$field3Data,
$field4Data
];
After you do that, you can then generate the spreadsheet using the following:
$sheet->getActiveSheet()
->fromArray(
$rows, // the data to set
NULL, // array values with this value will not be set
'A1', // top left coordinate of the worksheet range where we want to set these values (default is A1)
true // adds 0 to cell instead of blank if a 0 is the value
);
After doing the above, you can then add the code to create the table I posted and then save the file and you should be good.
Also, if you are in a situation where you still need to use the autofilter (for instance if you want to pre-filter the file on one or more columns which at this point you can't use a table when doing), you can make the autofilter call a bit easier.
// determine the the number of rows in the active sheet
$highestRow = $spreadsheet->getActiveSheet()->getHighestRow();
// get the highest column letter
$highestColumn = $spreadsheet->getActiveSheet()->getHighestColumn();
// set autofilter range
$spreadsheet->getActiveSheet()->setAutoFilter('A1:'.$highestColumn.$highestRow);
I realize the additional edit goes beyond the question, but figured I'd point it out since there are some built-in methods that you could use to reduce some of your code.

I have been a fervent reader of StackOverflow over the last few years, and I was able to resolve pretty much everything in VBA Excel with a search and some adapting. I never felt the need to post any questions before, so I do apologize if this somehow duplicates something else, or there is an answer to this already and I couldn't find it.
Now I`m considering Excel-JS in order to create an AddIn (or more), but have to say that Javascript is not exactly my bread and butter. Over the time of using VBA, I find that one of the most simple and common needs is to get the last row in a sheet or given range, and maybe less often the last column.
I've managed to put some code together in Javascript to get similar functionality, and as it is... it works. There are 2 reasons I`m posting this
Looking to improve the code, and my knowledge
Maybe someone else can make use of the code meanwhile
So... in order to get my lastrow/lastcolumn, I use global variables:
var globalLastRow = 0; //Get the last row in used range
var globalLastCol = 0; //Get the last column in used range
Populate the global variables with the function to return lastrow/lastcolumn:
function lastRC(wsName) {
return Excel.run(function (context) {
var wsTarget = context.workbook.worksheets.getItem(wsName);
//Get last row/column from used range
var uRange = wsTarget.getUsedRange();
uRange.load(['rowCount', 'columnCount']);
return context.sync()
.then(function () {
globalLastRow = uRange.rowCount;
globalLastCol = uRange.columnCount;
});
});
}
And lastly get the value where I need them in other functions:
var lRow = 0; var lCol = 0;
await lastRC("randomSheetName");
lRow = globalLastRow; lCol = globalLastCol;
I`m mainly interested if I can return the values directly from the function lastRC (and how...), rather than go around with this solution.
Any suggestions are greatly appreciated (ideally if they don't come with stones attached).
EDIT:
I've gave up on using an extra function for this as for now, given that it uses extra context.sync, and as I've read since this post, the less syncs, the better.
Also, the method above is only good, as long your usedrange starts in cell "A1" (or well, in the first row/column at least), otherwise a row/column count is not exactly helpful, when you need the index.
Luckily, there is another method to get the last row/column:
var uRowsIndex = ws.getCell(0, 0).getEntireColumn().getUsedRange().getLastCell().load(['rowIndex']);
var uColsIndex = ws.getCell(0, 0).getEntireRow().getUsedRange().getLastCell().load(['columnIndex']);
To break down one of this examples, you are:
starting at cell "A1" getCell(0, 0)
select the entire column "A:A" getEntireColumn()
select the usedrange in that column getUsedRange() (i.e.: "A1:A12")
select the last cell in the used range getLastCell() (i.e.: "A12")
load the row index load(['rowIndex']) (for "A12" rowIndex = 11)
If your data is constant, and you don't need to check lastrow at specific column (or last column at specific row), then the shorter version of the above is:
uIndex = ws.getUsedRange().getLastCell().load(['rowIndex', 'columnIndex']);
Lastly, keep in mind that usedrange will consider formatting as well, not just values, so if you have formatted rows under your data, expect the unexpected.
late edit - you can specify if you want your used range to be of values only (thanks Ethan):
getUsedRange(valuesOnly?: boolean): Excel.Range;
I have to say a big thank you to Michael Zlatkovsky who has put a lot of work, in a lot of documentation, which I`m far from finishing to read.
i am having difficulties with open xml sdk:
i am trying to generate excel file with several columns that have numbers and i want to have total sum at the end
i have tried to Generate Table Definition Part Content and inside define every column (id, name etC). If column has true for TotalColumn, it adds code (rough example)
var column = new TableColumn{
id = 1,
name = "example",
TotalsRowFunction = TotalsRowFunctionValues.Sum,
TotalsRowFormula = new TotalsRowFormula("=SUBTOTAL(109;[" + rowName + "])")
};
I can't get it to work, when i open excel it reports error, but it doesn't explicitly says what the problem is... I tried with microsoft validator but can't figure anything out...
I'd appreciate any help / example code since i can't google anything out
EDIT:
i use this at the end:
workbookPart.Workbook.CalculationProperties.ForceFullCalculation = true;
workbookPart.Workbook.CalculationProperties.FullCalculationOnLoad = true;
Why not use a cell formula?
E.g.
cell.DataType = new EnumValue<CellValues>(CellValues.Number);
cell.CellFormula = new CellFormula(string.Format("=SUBTOTAL({0};[{1}])", "109", rowName));
//This will force a full recalculation of all the cells
workbookPart.Workbook.CalculationProperties.ForceFullCalculation = true;
workbookPart.Workbook.CalculationProperties.FullCalculationOnLoad = true;
I ended using EPPlus for this as it seems to be working simple and efficient
I'm quite new to Matlab and I'm struggling trying to figure out how to properly preprocess my data in order to make some calculations with it.
I have an Excel table with financial log returns of many companies such that every row is a day and every column is a company:
I imported everything correctly into Matlab like this:
Now I have to create what's caled "rolling windows". To do this I use the following code:
function [ROLLING_WINDOWS] = setup_returns(RETURNS)
bandwidth = 262;
[rows, columns] = size(RETURNS);
limit_rows = rows - bandwidth;
for i = 1:limit_rows
ROLLING_WINDOWS(i).SYS = RETURNS(i:bandwidth+i-1,1);
end
end
Well if I run this code for the first column of returns everything works fine... but my aim is to produce the same thing for every column of log returns. So basically I have to add a second for loop... but what I don't get is which syntax I need to use in order to make that ".SYS" dynamic and based on my array of string cells containing company names so that...
ROLLING_WINDOWS(i)."S&P 500" = RETURNS(i:bandwidth+i-1,1);
ROLLING_WINDOWS(i)."AIG" = RETURNS(i:bandwidth+i-1,2);
and so on...
Thanks for your help guys!
EDIT: working function
function [ROLLING_WINDOWS] = setup_returns(COMPANIES, RETURNS)
bandwidth = 262;
[rows, columns] = size(RETURNS);
limit_rows = rows - bandwidth;
for i = 1:limit_rows
offset = bandwidth + i - 1;
for j = 1:columns
ROLLING_WINDOWS(i).(COMPANIES{j}) = RETURNS(i:offset, j);
end
end
end
Ok everything is perfect... just one question... matlab intellissense tells me "ROLLING_WINDOWS appears to change size on every loop iteration bla bla bla consider preallocating"... how can I perform this?
You're almost there. Use dynamic field names by building strings for fields. Your fields are in a cell array called COMPANIES and so:
function [ROLLING_WINDOWS] = setup_returns(COMPANIES, RETURNS)
bandwidth = 262;
[rows, columns] = size(RETURNS);
limit_rows = rows - bandwidth;
%// Preallocate to remove warnings
ROLLING_WINDOWS = repmat(struct(), limit_rows, 1);
for i = 1:limit_rows
offset = bandwidth + i - 1;
for j = 1:columns
%// Dynamic field name referencing
ROLLING_WINDOWS(i).(COMPANIES{j}) = RETURNS(i:offset, j);
end
end
end
Here's a great article by Loren Shure from MathWorks if you want to learn more: http://blogs.mathworks.com/loren/2005/12/13/use-dynamic-field-references/ ... but basically, if you have a string and you want to use this string to create a field, you would do:
str = '...';
s.(str) = ...;
s is your structure and str is the string you want to name your field.
Do we have an OLE2 command that can be used in Oracle Forms to return the number of columns in my excel file?!
I want to open an excel file from Oracle Forms and go through all columns and then just some the colomns.
Thanks!
To accomplish this I use a trivial solution, I iterate through all the col until the first empty one in the first line. Of course my file have always have the first row's col filled.
When I have a non filled row I use a constant, manually defined...
I iterate through like this:
Variant ws = /*(set your worksheet here)*/;
int col = 1;
for (int col = 1; toString(ws.olePropertyGet("Cell", row, col).olePropertyGet("value")) != ""); ++col)
//do stuff ++count;
It is dirty, but I never found a better way to do this, and I will follow this question to find a new one.
