I am working with Aspose slides to generate PPT in my application, I ran into a situation where I need to insert HTML text into Table Cell, I verified all blogs no one given answer to me. If any body know here please let me know. Thanks In advance.
You can use the TextFrame's paragraph associated with each cell to insert HTML using Aspose.Slides for .NET. Check the following code:
//Instantiate Presentation class that represents PPTX file
using (Presentation pres = new Presentation())
{
//Access first slide
ISlide sld = pres.Slides[0];
//Define columns with widths and rows with heights
double[] dblCols = { 250, 250};
double[] dblRows = { 150, 130, 130 };
//Add table shape to slide
ITable tbl = sld.Shapes.AddTable(100, 50, dblCols, dblRows);
//Set border format for each cell
foreach (IRow row in tbl.Rows)
foreach (ICell cell in row)
{
cell.BorderTop.FillFormat.FillType = FillType.Solid;
cell.BorderTop.FillFormat.SolidFillColor.Color = Color.Red;
cell.BorderTop.Width = 5;
cell.BorderBottom.FillFormat.FillType = FillType.Solid;
cell.BorderBottom.FillFormat.SolidFillColor.Color = Color.Red;
cell.BorderBottom.Width = 5;
cell.BorderLeft.FillFormat.FillType = FillType.Solid;
cell.BorderLeft.FillFormat.SolidFillColor.Color = Color.Red;
cell.BorderLeft.Width = 5;
cell.BorderRight.FillFormat.FillType = FillType.Solid;
cell.BorderRight.FillFormat.SolidFillColor.Color = Color.Red;
cell.BorderRight.Width = 5;
}
//Adding html text in text frame
tbl[0, 0].TextFrame.Paragraphs.AddFromHtml(#"<html><body><p><b>This text is bold</b></p>
<p><i>This text is italic</i></p><p>This is<sub> subscript</sub> and <sup>superscript</sup></p>
</body></html>");
//Write PPTX to Disk
pres.Save("d:\\data\\table_html.pptx", Aspose.Slides.Export.SaveFormat.Pptx);
}
P.S. I am working as social media developer at Aspose.

I've been trying to set the column width for my table, but it won't budge. I'm using NPOI from this git https://github.com/nissl-lab/npoi.
Currently, my code is:
FileStream stream = new FileStream(reportPath, FileMode.Open);
XWPFDocument doc = new XWPFDocument(stream);
XWPFTable table;
table = doc.CreateTable(1, 3);
table.SetColumnWidth(0, (ulong)1000);
table.SetColumnWidth(1, (ulong)2000);
table.SetColumnWidth(2, (ulong)3000);
using (var f = File.Create(reportPath)) doc.Write(f);
And the generated columns are in the same size having the smallest column size possible. Also, I'm trying to generate a DOCX file.
You have to set the table width type to make it work.
XWPFTable table1 = doc.CreateTable(1, 3);
var tblLayout1 = table1.GetCTTbl().tblPr.AddNewTblLayout();
tblLayout1.type = ST_TblLayoutType.#fixed;
table1.SetColumnWidth(0, 1000);
table1.SetColumnWidth(1, 2000);
table1.SetColumnWidth(2, 3000);
The above code works in NPOI 2.5.4
I am totally new to aspose. kindly help me to achieve the below requirement.
Requirement:- I am trying to make an application which can process an excel file and based on the excel data application will generate an output file( ppt extension).
Special instruction:- Please make a note I will provide ppt template and that template will have a certain placeholder where data will be inserted from uploaded excel.
Work In Progress:-
I have added both Aspose.Cells and Aspose.Slides dll to my project and wrote below PoC.
private void button1_Click(object sender, EventArgs e){
Workbook wb = new Workbook(#“C:\Users\Nilanjan\Desktop\Incident.xlsx”);
Worksheet ws = wb.Worksheets[0];
Cells cells = ws.Cells;
int col = CellsHelper.ColumnNameToIndex(“N”);
int last_row = ws.Cells.GetLastDataRow(col);
DataTable dt = wb.Worksheets[0].Cells.ExportDataTable(0, 0,
wb.Worksheets[0].Cells.MaxDataRow + 1, wb.Worksheets[0].Cells.MaxDataColumn + 1);
Presentation ps = new Presentation();
ISlide slide=ps.Slides[0];
slide=ps.Slides[1];
ps.Save(#“C:\Users\Nilanjan\Desktop\CocoonIncident1.pptx”,Aspose.Slides.Export.SaveFormat.Pptx );
}
Till now I have tried to upload the excel into my code and after processing it I was able to fill a DataTable with the excel data, now next step is to fill the ppt-template with that DataTable data. Please help me to achieve this functionality or please suggest a suitable workaround. Let me know if ppt template or excel file is required.
#Nilanjan,
I have observed your requirements for adding DataTable to PowerPoint slides. There is no direct way available to add DataTable in PowerPoint slides. You need to access every cell in DataTable and add that in PowerPoint slides by following mechanism supported by PowerPoint or Aspose.Slides. I suggest you to please try using following sample code on your end.
public static void DataTableToSlides()
{
String path = #"C:\Aspose Data\";
System.Data.DataTable table = new System.Data.DataTable();
table.Columns.Add("Term", typeof(string));
table.Columns.Add("Value", typeof(float));
table.Rows.Add(#"Term 16", 1.5);
table.Rows.Add(#"Term 15", 0.7);
table.Rows.Add(#"Term 14", 0.7);
table.Rows.Add(#"Term 13", 0.6);
table.Rows.Add(#"Term 12", 0.6);
Presentation pres = new Presentation();
ISlide slide = pres.Slides[0];
double[] colWidth = { 100, 100 };
double[] rowHeight = { 40};// 40, 40,40,40,40 };//1 row additional to hold the headers
ITable slidesTable = slide.Shapes.AddTable(100, 10, colWidth, rowHeight);
slidesTable[0, 0].TextFrame.Text = table.Columns[0].ColumnName;
slidesTable[1, 0].TextFrame.Text = table.Columns[1].ColumnName;
for (int i=0;i<table.Rows.Count;i++)
{
DataRow row = table.Rows[i];
slidesTable.Rows.AddClone(slidesTable.Rows[0], false);
slidesTable[0, i + 1].TextFrame.Text = row[0].ToString();
slidesTable[1, i + 1].TextFrame.Text = row[1].ToString();
}
pres.Save(path + "Saved.pptx",Aspose.Slides.Export.SaveFormat.Pptx);
}
I am working as Support developer/ Evangelist at Aspose.
Many Thanks.
I'm using NPOI Excel Library to generate a Excel file, in that Excel file i'm explicitly define column type for Columns like Date,String etc.
Im using the following code to achive this.
var row = sheet.CreateRow(currentNPOIRowIndex++);
for (var colIndex = 0; colIndex < exportData.Columns.Count; colIndex++)
{
ICell cell = null;
cell = row.CreateCell(colIndex);
if (exportData.Columns[colIndex].DataType == typeof(DateTime))
{
if (exportData.Rows[rowIndex][colIndex].ToString() != "")
{
cell.SetCellValue((DateTime)exportData.Rows[rowIndex][colIndex]);
cell.CellStyle = (NPOI.HSSF.UserModel.HSSFCellStyle)book.CreateCellStyle();
cell.CellStyle.DataFormat = book.CreateDataFormat().GetFormat("yyyyMMdd HH:mm:ss");
cell = null;
}
else
cell.SetCellValue(exportData.Rows[rowIndex][colIndex].ToString());
}
else
cell.SetCellValue(exportData.Rows[rowIndex][colIndex].ToString());
}
}
The above code works fine for 42 rows i.e. it correctly set the Column Type,but after 42 rows Column Type doesn't apply.
Any help will be highly appreciated.
you'll required to set default column style if you want to set column format for all cells of that column. Please see the below example from xssf format. Syntax may differ for your hssf format but it will give you idea what you are missing.
I am providing you from my working code. I am using NPOI version 2.2.1.0.
can you comment line //cell = null;
XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = (XSSFSheet)workbook.CreateSheet("Template");
XSSFFont defaultFont = (XSSFFont)workbook.CreateFont();
defaultFont.FontHeightInPoints = (short)10;
XSSFCellStyle headerStyle = (XSSFCellStyle)workbook.CreateCellStyle();
headerStyle.WrapText = true;
XSSFCellStyle defaultStyle = (XSSFCellStyle)workbook.CreateCellStyle();
XSSFDataFormat defaultDataFormat = (XSSFDataFormat)workbook.CreateDataFormat();
defaultStyle.SetDataFormat(defaultDataFormat.GetFormat("000-000-0000"));
defaultStyle.FillBackgroundColor = IndexedColors.LightYellow.Index;
defaultStyle.FillForegroundColor = IndexedColors.LightTurquoise.Index;
defaultStyle.SetFont(defaultFont);
var row = sheet.CreateRow(0);
for (int headerCount = 0; headerCount < headers.Count(); headerCount++)
{
row.CreateCell(headerCount).SetCellValue(headers[headerCount]);
row.Cells[headerCount].CellStyle = headerStyle;
sheet.SetDefaultColumnStyle(headerCount, defaultStyle);
}
I generate an Excel sheet which contains data formatted like so:
IOW, the "Total Packages", "Total Purchases", "Average Price", and "% of Total" values are located in a column of their own (Data) for each overarching (or sidearching) description.
When I PivotTablize this data, it places these values beneath each description:
This makes sense, but those accustomed to the previous appearance want it to be replicated in the PivotTable. How can I shift the Description "subitems" in the PivotTable to their own column?
This is the code I use to generate the PivotTable:
private void PopulatePivotTableSheet()
{
string NORTHWEST_CORNER_OF_PIVOT_TABLE = "A6";
AddPrePivotTableDataToPivotTableSheet();
var dataRange = rawDataWorksheet.Cells[rawDataWorksheet.Dimension.Address];
dataRange.AutoFitColumns();
var pivotTable = pivotTableWorksheet.PivotTables.Add(
pivotTableWorksheet.Cells[NORTHWEST_CORNER_OF_PIVOT_TABLE],
dataRange,
"PivotTable");
pivotTable.MultipleFieldFilters = true;
pivotTable.GridDropZones = false;
pivotTable.Outline = false;
pivotTable.OutlineData = false;
pivotTable.ShowError = true;
pivotTable.ErrorCaption = "[error]";
pivotTable.ShowHeaders = true;
pivotTable.UseAutoFormatting = true;
pivotTable.ApplyWidthHeightFormats = true;
pivotTable.ShowDrill = true;
// Row field[s]
var descRowField = pivotTable.Fields["Description"];
pivotTable.RowFields.Add(descRowField);
// Column field[s]
var monthYrColField = pivotTable.Fields["MonthYr"];
pivotTable.ColumnFields.Add(monthYrColField);
// Data field[s]
var totQtyField = pivotTable.Fields["TotalQty"];
pivotTable.DataFields.Add(totQtyField);
var totPriceField = pivotTable.Fields["TotalPrice"];
pivotTable.DataFields.Add(totPriceField);
// Don't know how to calc these vals here, so have to grab them from the source data sheet
var avgPriceField = pivotTable.Fields["AvgPrice"];
pivotTable.DataFields.Add(avgPriceField);
var prcntgOfTotalField = pivotTable.Fields["PrcntgOfTotal"];
pivotTable.DataFields.Add(prcntgOfTotalField);
}
So there is one RowField ("MonthYr") with values such as "201509" and "201510", one ColumnField ("Description") and four DataFields, which align themseles under the Description column field. I want to shift those four fields to the right, to their own column, and the Description label to be vertically centered between those four values to their left. [How] is this possible?
Try changing the layout of your table with
pivotTable.RowAxisLayout xlTabularRow
pivotTable.MergeLabels = True
this is the result:
A little script in C# with Interop.Excel. Included the using ;)
using Microsoft.Office.Interop.Excel;
using System.Runtime.InteropServices;
using Excel = Microsoft.Office.Interop.Excel;
var excelApp = new Excel.Application();
Excel.Workbook wb = excelApp.Workbooks.Open(#"e:\42\TestSO.xlsx");
Worksheet ws = wb.Worksheets["SheetName"];
PivotTable pt = ws.PivotTables("DynamicTableName");
pt.RowAxisLayout(XlLayoutRowType.xlTabularRow);
pt.MergeLabels = true;
wb.Save();
wb.Close();
Marshal.ReleaseComObject(ws);
It's all about PivotTable layout / design... here's the manual way - Salvador has the VBA way :)...
Is there a way in MigraDoc to make an entire table cell a link? I have a tabular table of contents, and the page number is difficult to click. I would prefer if the entire cell was clickable to navigate to a specified page. Here is an example of my code:
// Create the table within the document
var document = new Document();
var section = document.AddSection();
var table = section.AddTable();
// Create a column in the table
var column = table.AddColumn();
column.Width = "2cm";
// Create a row in the table
var row = table.AddRow();
row.Height = "1cm";
// Add a hyperlink to the appropriate page
var paragraph = row.Cells[0].AddParagraph();
var hyperlink = paragraph.AddHyperlink("MyBookmarkName");
hyperlink.AddPageRefField("MyBookmarkName");
...
// Create the bookmark later in the document
I'm afraid there is no easy way to make the whole cell clickable. I haven't tried it myself, but you can add images (visible or transparent) or text to the hyperlink.
This will make the clickable area bigger - and if you use e.g. blue underlined text there will be a visual hint that the text is clickable.
I was inspired by the answer from the PDFsharp Team to try and fill the cell with a blank hyperlink image, with text over the hyperlink. Since my ultimate goal was to actually make an entire row a hyperlink, I came up with the following solution.
First, add an additional zero-width column prior to the first column in the table that you want to be a hyperlink. Next, add a paragraph, hyperlink, and transparent 1-pixel image to each zero-width cell. Specify the image height and width to fill however many table cells you want to be a link. Also, be sure to set the font size of the paragraph containing the link to nearly zero (zero throws an exception, but images are aligned on the font baseline, so you need a very small number to prevent the paragraph from being larger than the image).
Note that a zero-width column, even with borders, does not change the apparent border width when viewing the resulting PDF. The following code illustrates my approach:
// Declare some constants
var _rowHeight = new Unit(.75, UnitType.Centimeter);
// Create the document, section, and table
var document = new Document();
var section = document.AddSection();
var table = section.AddTable();
// Format the table
table.Rows.Height = _rowHeight;
table.Rows.VerticalAlignment = VerticalAlignment.Center;
// Define the column titles and widths
var columnInfos = new[] {
new { Title = "Non-Link Column", Width = new Unit(8, UnitType.Centimeter) },
new { Title = "" , Width = new Unit(0 ) },
new { Title = "Link Column 1" , Width = new Unit(8, UnitType.Centimeter) },
new { Title = "Link Column 2" , Width = new Unit(8, UnitType.Centimeter) },
};
// Define the column indices
const int colNonLink = 0;
const int colHyperlink = 1;
const int colLink1 = 2;
const int colLink2 = 3;
// Create all of the table columns
Unit tableWidth = 0;
foreach (var columnInfo in columnInfos)
{
table.AddColumn(columnInfo.Width);
tableWidth += columnInfo.Width;
}
// Remove the padding on the link column
var linkColumn = table.Columns[colHyperlink];
linkColumn.LeftPadding = 0;
linkColumn.RightPadding = 0;
// Compute the width of the summary links
var linkWidth = tableWidth -
columnInfos.Take(colHyperlink).Sum(ci => ci.Width);
// Create a row to store the column headers
var headerRow = table.AddRow();
headerRow.Height = ".6cm";
headerRow.HeadingFormat = true;
headerRow.Format.Font.Bold = true;
// Populate the header row
for (var colIdx = 0; colIdx < columnInfos.Length; ++colIdx)
{
var columnTitle = columnInfos[colIdx].Title;
if (!string.IsNullOrWhiteSpace(columnTitle))
{
headerRow.Cells[colIdx].AddParagraph(columnTitle);
}
}
// In the real code, the following is done in a loop to dynamically add rows
var row = table.AddRow();
// Populate the row header
row.Cells[colNonLink].AddParagraph("Not part of link");
// Change the alignment of the link cell
var linkCell = row.Cells[colHyperlink];
linkCell.VerticalAlignment = VerticalAlignment.Top;
// Add a hyperlink that fills the remaining cells in the row
var linkParagraph = linkCell.AddParagraph();
linkParagraph.Format.Font.Size = new Unit(.001, UnitType.Point);
var hyperlink = linkParagraph.AddHyperlink("MyBookmarkName");
var linkImage = hyperlink.AddImage("Transparent.gif");
linkImage.Height = _rowHeight;
linkImage.Width = linkWidth;
// Populate the remaining two cells
row.Cells[colLink1].AddParagraph("Part of link 1");
row.Cells[colLink2].AddParagraph("Part of link 2");
// Add a border around the cells
table.SetEdge(0, 0, columnInfos.Length, table.Rows.Count,
Edge.Box | Edge.Interior, BorderStyle.Single, .75, Colors.Black);
The result of the above code is a document containing a table with 2 rows, 3 visible columns, where the entirety of the last two cells in the final row are a hyperlink to "MyBookmarkName". Just for reference, I did modify the PDFSharp source code according to the advice here to remove borders around hyperlinks, which looked wonky at certain zoom levels in Adobe Acrobat Reader.
