To insert a table, click on the 'Insert table' button on the toolbar.
Select the template you want to add a table to and it will bring up a table properties box.
Here, you can choose the table you wish to add from the 'Table Name' drop-down menu.
You can add columns to the table in the table headers box. The 'Header Text' is where you put the title of the table column, and the 'Field Name' is where you choose the tag which relates to the field within Clik. You can choose these from their drop-down menus.
