Bug Description:
Removing a Table Column causes wrong selected column

When removing a column from a table, DefaultTableColumnModel is adjusting the selection (implying that a column that is not selected is selected) then removing the column.

Run Code and press the remove column button
Expected: Label to say 'Selected Column: column 2'
Actual: Label says 'Selected Column: column 1'
