Text direction in apache poi - java

How to make the text direction in Apache poi as Vertical.
I tried Vertical alignment. I am not able to get the desired results.
I don't want to rotate the text.
Something like :
T
E
X
T

You have to create a cellStyle, where You have a method setRotation(short rotation). Subsequently apply the cellstyle to Your cell.
docs, for setRotation
https://poi.apache.org/apidocs/org/apache/poi/xssf/usermodel/XSSFCellStyle.html#setRotation(short)

Java- Apache POI XSSF - Custom RGB Cellbackground not working

I want to use a custom RGB color (38,38,38) for my cell backgroundcolor.
For that I use this code:
IndexedColorMap colorMap = wb.getStylesSource().getIndexedColors();
XSSFColor customtablegrey = new XSSFColor(new java.awt.Color(38,38,38), colorMap);
cellFormat1.setFillForegroundColor(customtablegrey.getIndex());
cellFormat1.setFillPattern(FillPatternType.SOLID_FOREGROUND);
But all I get is a black background. Why and how can I change it?
Best Regards,
Christian
That's true. IndexedColorMap is useless for XSSFColors. XSSFColors are not indexed colors. In Office Open XML custom colors are stored as RGB directly in the XML. They are not stored in any kind of color map.
Setting XSSFColors as fill foreground color to cell styles is possible using XSSFCellStyle.setFillForegroundColor(XSSFColor color) only. It cannot be set using CellStyle.setFillForegroundColor(short fg).
So cellFormat1.setFillForegroundColor(customtablegrey) should work when cellFormat1 is a XSSFCellStyle.

How to check if text fits into cell?

I am using apache poi 3.17 for generating *.xlsx files.
For a reason I don't know, the setWrapText(true) (merged cells) function of the class CellStyleDesc does not trigger the resizing of the row's height as it should be.
Could someone help me?
