AutoCad :: Original Dialogue Box To Edit Existing Table

Is there a way to bring up the original dialogue box to edit an existing table? (TABLE brings the "Insert Table" dialogue box that lets you set number of rows and columns, it's this menu that I would like to bring up to revise existing table settings).

It seems hard to edit a table once it exists.

The reason I'm looking to do this is because I have an excel table linked (which I scaled to be larger) but every time I update the table to include new information it brings the new text in at the original text size (very small). I figure I could solve this by going back to the original table settings and setting an area on the sheet to update rather than selecting "Entire sheet"...
