If i have more than one row, I can do that, but I have a form with 1 row and 4 columns. I added a new column but I could not move any of the data from an existing column to the new column. I had to add a new row, add an attribute to that, then drag that to the desired column.
Just like there is an UP and DOWN arrow there should be a Left and Right arrow to move a column.
