Error adding rows to data table

[Cliff Carson]

Have a simple two item chart and when I try to add rows to the data table the columns expand. Display the data table and try to move the cursor to the bottom so that I can add a row and as soon as I go to the second row two empty columns are added. When I get to the bottom the screen fills with empty columns.
