Question

I am a beginner with Apache POI library.

in VBA, I know I can select and bold the whole worksheet with following code

Dim ws As Worksheet
Set ws = ThisWorkbook.Sheets(1)
ws.Cells.Font.Bold = True

May I know how to select and bold the whole sheet by coding with Apache POI library?

thanks

Answer 1

There is a pretty good example on this link.

Sheet sheet = wb.createSheet("test");
CellStyle cs = wb.createCellStyle();
Font f = wb.createFont();
f.setBoldweight(Font.BOLDWEIGHT_BOLD);
cs.setFont(f);
sheet.setDefaultColumnStyle(1,cs); //set bold for column 1
