Ah, I did not see the Modify Table icon in the help file.  But I've added it now and there seems to still be a couple of problems.

 

For example, if I try changing the number of rows and columns, it doesnt apply it to the table (perhaps that is just how it works).  It also doesn't retain the alignment value.

 

Also, it seems more intuitive to have the Modify Table appear when double-clicking on a table rather than a New Table window(null being passed to insert_table.asp).

 

Thanks,
Nathan
