To add a table to a page, hit the "Add" icon under the Tables area on the Custom Excel conversion panel. Then use your mouse to add a new table.
To delete an already created table, click on the "Delete" icon and then left click on the table you wish to delete.
If you would like the conversion algorithm to recalculate the table structure for tables within a given page range, you can hit the "Replot" icon and it will automatically recalculate the column structure for all tables within the active page range. Tables can only be vertically spaced they cannot be side-by-side.
