Use the Column Chooser to select which columns are visible in your grid and in which order.
The Column Chooser is for showing/hiding the columns in your grid.
If you wish to control which rows are visible, use one of the Search Functions instead.
To add and remove columns to suit your own requirements:
Open the Column Chooser popup.
The Selection Tool appears.
Use the buttons to manage column visibility and order as required. The grid will update automatically so that it shows/hides its columns in line with the changes you make.
