When viewing any table, you can move rows and columns by dragging-and-dropping (i.e., click on the row or column of interest and drag it to where you would like it to be). Merging is done in the same way, except that you release your mouse button (i.e., ‘drop’) one category onto another. Similarly, by holding down the control key (Ctrl) on your keyboard, you can copy a category. Additional manipulation of the table is possible using the Table Context Menu and by changing the underlying data (see Modifying variables and questions).
