How to add left and right column

Hello,
Can you please show me how to add a left and right column?

Thanks.
Jenny.

You need to include the board's content in the table.

But I like to have vertical column on all pages. Not only on the index pages, I want all pages.
Thanks.
Jenny.

This is nearly what the above solution provides. "main_header.html" states for the file templates/main_header.html which you need to edit. The same for main_footer.html. If you split the general table between main_header.html and main_footer.html, this is what you would want to achieve.
