Tables contain a lot of code. Thanks to the 'table edit' function, you can avoid the code. Clicking on 'Table edit' gives you an easy interface to adjust the content of the table
Above each table, you will see two links: 'edit' and 'table edit':
If you click on the plain 'edit' link, this is what you will see:
Clicking on the 'table edit' link will bring you to this page (the real page is, of course, bigger!):
This looks a lot easier, doesn't it? On this page, you only need to type some text in the square text fields - a lot easier than the encoding shown in the image before. You do not need to adjust the values in the fields above the square text fields (alignment, width, etc.)
Just bear in mind: To edit a table the easy way, click on the 'table edit' link, not on the plain 'edit' link.
