CorelDRAW Graphics Suite X5 :: Table Tool - Right Mouse Click Options Are Greyed Out

I've spent some time designing a chart using the table tool.  Now I want to adjust some column widths and add some text. 

However, the mouse keeps trailing a small table icon, and all it will let me do is insert another table.  I can't enter text, or highlight a row or column, for example.  Most of the right mouse click options are greyed out. 

How do I change from this mode for the mouse, with the Table icon switched on, to other modes where I can do other things with the table I have already created?(If I create a new table below this existing table, all is well.  However, I can't grab the content in the earlier table to paste it into the new one.)
