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

Can I know how to select and bold the entire table by coding using the Apache POI library?

Solution

There is a good example of 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
