You can insert tables using <list> tag in your comments. It is recommended to use comment editor for adding or editing tables. Normally, the <list> tag only allows one or two table columns. However, you can extend the <list> syntax and use any number of columns. You can do it also in WYSIWYG comment editor.
Normally, the table can have only one column (using <term>) or two columns (using <term> and <description>).
Previous example creates a table with one heading row and one normal row and two columns:
To add more columns, just add another <description> tags inside <listheader> or/and <item> tags.
Previous example creates table with one heading row and one normal row and three columns:
Tables with more than two columns will work correctly in WYSIWYG comment editor and all output formats.
