Is there any other way to merge cells in Excel using Apache POI library?
I was trying using the following, but its not working
// selecting the region in Worksheet for merging data
CellRangeAddress region = CellRangeAddress.valueOf("A" + rowNo + ":D"
+ rowNo);
// merging the region
sheet1.addMergedRegion(region);
You can use sheet.addMergedRegion(rowFrom,rowTo,colFrom,colTo);
example sheet.addMergedRegion(new CellRangeAddress(1,1,1,4));
will merge from B2 to E2. Remember it is zero based indexing (ex. POI version 3.12).
