With JExcel, you can hide/unhide columns like you would do in Excel.
(If you hide a column, it will not effect the datasource.)
To hide a column, simply click on the icon (1) the select the option 'hide' (2).
And to unhide all the hidden columns just click on the link in the right-upper corner (1).
To see which columns are hidden hover on the link (2).
If you want to display a new column from the datasource:
- Click on the sign in the right upper corner (1)
- you can search for the right column name (2)
- select the column you want to add by clicking in the checkbox (3)
The added column will be at the right end of your table!
