Need to shift the table to right in apache poi word - apache-poi
I have created the table in apache POI, need to create another similar table but shifted right:
But I want to create similar another table to the right but at bottom.
Do we have a setting in XWPFTable to set the alignment for the table to shift right or Do i need to re-build the entire table again

You can indent the table using the low level org.openxmlformats.schemas.wordprocessingml.x2006.main.* classes.
XWPFTable table = document.createTable(3,3);
// set indentation of the table
CTTblWidth tableIndentation = table.getCTTbl().getTblPr().addNewTblInd();
tableIndentation.setW(BigInteger.valueOf(720)); //720 TWentieths of an Inch Point (Twips) = 720/20 = 36 pt = 36/72 = 0.5"
tableIndentation.setType(STTblWidth.DXA);
But there also is XWPFTable.setTableAlignment. Using that you can align the whole table.
XWPFTable table = document.createTable(3,3);
table.setTableAlignment(TableRowAlign.RIGHT); //table right aligned
For apache poi versions prior 4.1.1 the following low level approach can be used to right align the table:
XWPFTable table = document.createTable(3,3);
table.getCTTbl().getTblPr().addNewJc().setVal(STJc.RIGHT); //table right aligned

Result:
This answer is about your problems with your provided complete example:
First: Aligning by using bidirectional text settings so table is displayed in a right to left direction is not to recommend. This only should be used for langauges which really needs bidirectional text, hebrew or arabic for example. So your table aligning rather should be like:
private static void setTableAlign(XWPFTable table, STJc.Enum align) {
CTTbl cttblp = table.getCTTbl();
CTTblPr cttblpr = (cttblp.getTblPr() == null ? cttblp.addNewTblPr() : cttblp.getTblPr());
CTJc ctjc = (cttblpr.isSetJc() ? cttblpr.getJc() : cttblpr.addNewJc());
ctjc.setVal(align);
}
Second: When cells were merged, then the column width for the new merged cell should be set. Else Word will possibly use kinds of unwanted automatism to determine column widths. So for example:
...
mergeCellHorizontally(table, 2, 4, 7);
setColumnWidth(table, 2, 4, colunmWidths[4]+colunmWidths[5]+colunmWidths[6]+colunmWidths[7]);
...
and
...
mergeCellHorizontally(table, row, 1, 7);
setColumnWidth(table, row, 1, colunmWidths[1]+colunmWidths[2]+colunmWidths[3]+colunmWidths[4]+colunmWidths[5]+colunmWidths[6]+colunmWidths[7]);
...

handling a view frustum when not facing the object
i have made a view frustum from scratch in javascript. i have been having trouble with objects that the camera is place within and also facing away from.
an example of the problem is below
ive been stuck on this for months with little help, chatgpt recommended that i switch to a right handed corodinate system, so i did, but it didnt seem to fix the problem.
my proccess for putting pixels on the screen is described below
step 1 = cross product with camera matrix
step 2 = cross product with projection matrix
step 3 = divide co-ordinates by their own w co-ord (normalize w to 1)
step 3.5 = im currently skipping culling. culling would go here, but since my object is made of multiple vertices i cant cull a vertex just because its offscreen as it forms part of a whole object, and that would deform the rest of the object
step 4 = cross product with projection to screen matrix
below shows how the co-ordinates of 1 vertex changes with each step
co-ordinates of vertex before projection
[5.00,9.00,10.00,1.00]
good projection (tile is good)
step 1 = [5, 9, -4.799999999999979, 10]

pixels = 227.32369676914016, 10.817345815547753
does anyone know which step could be wrong or need changing in situation 2 and 3? and why?
below is a minimal (i know its 500 lines... but its about as minimal as i can get it) just open it in a browser and use wasd to control it.

To set table row height in XWPFTable table the height rule also must be set additional to the height itself. For example:
table.getRow(0).setHeight(12*20); // row height in twentieth pt
table.getRow(0).getCtRow().getTrPr().getTrHeightArray(0).setHRule(STHeightRule.EXACT); // height rule exact
There are following height rules possible:
AT_LEAST: At least the given height. Higher if needed but not lesser.
AUTO: The default. Default height of one default paragraph height inclusive spacing before and after. As high as needed dependent on content.
EXACT: Exact the given height. Content possibly gets cut of.
Note, a 0 value for XWPFTableRow.setHeight will not be accepted in combination with EXACT height rule. This falls back to default AUTO height then.
According to your code sample:
...
private static void prepareQuotaList(XWPFTable table) {
int count = 0;
for (int row = 0; row < 4; row++) {
XWPFTableRow tableRow = table.getRow(row);
tableRow.setHeight(12*20); // row height = 12 pt
tableRow.getCtRow().getTrPr().getTrHeightArray(0).setHRule(STHeightRule.EXACT); // height rule exact
for (int col = 0; col < 3; col++) {
setCellBorders(tableRow.getCell(col), new STBorder.Enum[]{STBorder.NIL, STBorder.NIL, STBorder.NIL, STBorder.NIL});
}
...
}
...
As said above there are only the three height rules possible. So if the goal is having table rows as high as their content but not more ore less, then height rule AUTO must be used. Then the paragraph's height determines the row height. Note a XWPFParagraph might have set spacing before, between and after the text rows. So you might have to set:
...
paragraph.setSpacingAfter(0);
paragraph.setSpacingBetween(1); // don't set this 0
paragraph.setSpacingBefore(0);
...
This must be set for each table cell which contains paragraphs already. So if needed for the whole table, then:
XWPFTable table = document.createTable(4, 8);
for (XWPFTableRow row : table.getRows()) {
for (XWPFTableCell cell : row.getTableCells()) {
for (XWPFParagraph p : cell.getParagraphs()) {
p.setSpacingAfter(0);
p.setSpacingBetween(1); // don't set this 0
p.setSpacingBefore(0);
}
}
}
Create a table in powerpoint with Apache poi
I'm using Java v8 and "org.apache.poi" and "poi-ooxml" (both are version 3.9). I'm trying to create a powerpoint with a slide on it which contains a table.
I can get the powerpoint file to create ok but the slide is empty but for a small black box in the top right corner. I'm guessing I'm missing something small but can't see what it is. I've tried some examples from the web and they look to be the same as what I'm seeing.
This is what I see in the Powerpoint slide:
My code is as below:
XMLSlideShow powerpoint = new XMLSlideShow();
XSLFSlide slide = powerpoint.createSlide();
XSLFTable table = slide.createTable();
table.setAnchor(new Rectangle(50, 50, 800, 800));
int numColumns = 3;
int numRows = 5;
XSLFTableRow headerRow = table.addRow();
headerRow.setHeight(50);
// header
for (int i = 0; i < numColumns; i++) {
XSLFTableCell th = headerRow.addCell();
XSLFTextParagraph p = th.addNewTextParagraph();
p.setTextAlign(TextAlign.CENTER);
XSLFTextRun r = p.addNewTextRun();
r.setText("Header " + (i + 1));
r.setFontSize(20);
r.setFontColor(Color.white);
th.setFillColor(new Color(79, 129, 189));
table.setColumnWidth(i, 150);
}
// rows
for (int rownum = 0; rownum < numRows; rownum++) {
XSLFTableRow tr = table.addRow();
tr.setHeight(50);
// header
for (int i = 0; i < numColumns; i++) {
XSLFTableCell cell = tr.addCell();
XSLFTextParagraph p = cell.addNewTextParagraph();
XSLFTextRun r = p.addNewTextRun();
r.setText("Cell " + (i + 1));
if (rownum % 2 == 0) {
cell.setFillColor(new Color(208, 216, 232));
}
else {
cell.setFillColor(new Color(233, 247, 244));
}
}
}
try {
try (FileOutputStream out = new FileOutputStream("c:\\myFile.pptx"))
{
try {
powerpoint.write(out);
} catch (IOException e) {
e.printStackTrace();
}
}
} catch (IOException e) {
e.printStackTrace();
}
Any thoughts/guidance would be really appreciated.

Handle Null Value In Gridview During Exporting To Excel
I am working with a C# Windows application. Trying to export data from gridview to Excel , but when the gridview column is empty I do get error message.
How to handle that? Please help
This is my code
// Store Header from Gridview to Excel
for (int i = 1; i < dgvresult.Columns.Count + 1; i++)
{
Excel.Cells[1, i] = dgvresult.Columns[i - 1].HeaderText;
}
// Loop rows and columns of Gridview to store to Excel
for (int i = 0; i < dgvresult.Rows.Count; i++)
{
for (int j = 0; j < dgvresult.Columns.Count; j++)
{
Excel.Cells[i + 2, j + 1] = dgvresult.Rows[i].Cells[j].Value.ToString(); // Here when the value in Gridview is empty error how to handle this
}
}
Excel.ActiveWorkbook.SaveCopyAs("D:\\Asserts.xls");
Excel.ActiveWorkbook.Saved = true;
Excel.Quit();
MessageBox.Show("Excel file created,you can find the file D:\\Asserts.xls");
Excel.Visible = true;
Found solution do a checking by code below
private void btnexport_Click(object sender, EventArgs e)
{
Microsoft.Office.Interop.Excel.ApplicationClass Excel = new Microsoft.Office.Interop.Excel.ApplicationClass();
Excel.Application.Workbooks.Add(Type.Missing);
Excel.Columns.ColumnWidth = 14;
// Store Header from Gridview to Excel
for (int i = 1; i < dgvresult.Columns.Count + 1; i++)
{
Excel.Cells[1, i] = dgvresult.Columns[i - 1].HeaderText;
}
// Loop rows and columns of Gridview to store to Excel
for (int i = 0; i < dgvresult.Rows.Count; i++)
{
for (int j = 0; j < dgvresult.Columns.Count; j++)
{
if (dgvresult.Rows[i].Cells[j].Value == null)
{
dgvresult.Rows[i].Cells[j].Value = "NA"; // Where the gridview is empty do a checking and Insert NA
}
Excel.Cells[i + 2, j + 1] = dgvresult.Rows[i].Cells[j].Value.ToString();
}
}

Just replace newPdfTable.HeaderRows = 1; to newPdfTable.HeaderRows = 0; and one more thing iTextSharp.text.pdf.PdfPCell cell = new iTextSharp.text.pdf.PdfPCell(image); and one more parameter as true iTextSharp.text.pdf.PdfPCell cell = new iTextSharp.text.pdf.PdfPCell(image,true);
