Doesn't change column but changes row to a new location. When you copy or fill a formula to other cells, the absolute reference (column) stays the same while the relative reference (row) adjusts to the new location. For example, if you copy the formula =$A1+3 from cell B2 to C3, the formula in C3 changes to =$A2+3.
