Hide/Unhide columns

With JExcel, you can hide/unhide columns like you would do in Excel. This way of hiding the columns will not affect the datasource which makes it possible for every user to hide columns in his/her workbook to create unique view.

If you want to display a new column from the datasource:

Click on the Columns icon in the right upper corner
Use the search box to find the right column name
Select the column you want to add by clicking in the checkbox
The added column will be at the right end of your table!

If you don't want to display a column (remove it from the datasource) simply uncheck that from the list.
