Now we will see to use the UnderlineStyle of Cell’s on Excel Sheet Using JExcel APIs.

For using the underline style in a cell of an excel worksheet we should use have the jxl.write.WritableFont.

 WritableFont wfobj=new WritableFont(WritableFont.TIMES, 10, WritableFont.BOLD, false, UnderlineStyle.NO_UNDERLINE,Colour.BLUE);
        WritableCellFormat cfobj=new WritableCellFormat(wfobj);

In the above code snippet, we have set the UnderlineStyle as NO_UNDERLINE i.e. it means that there will be underlining in the texts in the cells of the sheet.
