1. Click on the column header(say 10th column in the result set) that need to be moved, keep the left mouse button pressed, this would be change the background of the column header to be suppressed.
2. With the left mouse button pressed drag the column header and start moving it to the column header where it needs to be placed.
3. When the column header which is being moved is on top of the column header(the current 2nd column header) where it needs to be placed, release the left mouse button.
4. This would complete the movement of the column header, now the 10th column would be in the second place, the current second column would be moved by one to the third place.
