Shuffle Columns command
The Shuffle Table Columns dialog allows you to reorder columns within a table. It is accessed by placing the cursor in a table while in Design mode and clicking Table | Shuffle Columns on the Home tab.
The dialog displays the table with each column under a numbered header.
When you click a column, arrows pointing to the left and to the right of the column appear on the header indicating which directions the column can be moved. If an arrow is not present in the header, the column cannot be moved in that direction.
The base row indicator 
allows you to select the base row of the column you want to reorder by clicking the left side of the dialog box to move the base row indicator. The base row defines the criteria used to shuffle columns. For example, if you select a row that contains some merged squares, the group of merged squares is shuffled as a whole. If the base row does not contain merged squares but the column is part of a merged square, you can only move the column within the merged squares.
Note: All cells within a table will be re-referenced after a Table Column Shuffle.
