I have been using jxls for my Excel based reports. I am facing a problem with a particular report where the original template has 31 columns for days in a month followed by columns that do certain calculations based on the data in the day columns.
While I am able to insert data in the 31 columns, the problem is that the columns beyond keep shifting right.
I want to be able to insert data in the existing column space and not create new columns. Appreciate help with this.
