When using table widgets in your web screen, you can manage the cells, columns, and rows of that table. When you insert the table, you specify the number of columns that the table has, but you can, afterwards, add or delete columns, and change the column order.
These operations are available on the Table Toolbar or when right-clicking inside a table.
Open the insert columns drop list on the Table Toolbar, and select whether to insert a column to the Left or to the Right of the table cell where your cursor is currently positioned. By default, if you press the insert column button on the Table Toolbar it will insert a column to the left.
The Delete column operation deletes the column of the cell where your cursor is positioned on the Content Canvas.
The and buttons allows you to change the column order of the column where your cursor is positioned on the Content Canvas.
These operations are also available when you are managing the Table Records widget.
