If you would like a table to be displayed in a post or page to display information in an organised way.
The easiest way to do this is to first create a table with Microsoft Word and then copy it to your clipboard.
In WordPress, within the post or page editor, click the Show/Hide Kitchen Sink button (just to the left of the yellow S2 button) to bring up additional editing options. To paste the table into WordPress you need to click the Paste from Word button (arrowed).
A pop-up box will appear to paste your table into (CTRL-V), click insert and the table will appear in your post or page.
Remember to click on the Publish button.
