A row is a series of data banks laid out in a horizontal fashion in a table or spreadsheet. For example, in the picture below the row headers (row numbers) are numbered 1, 2, 3, 4, etc. As you can see from the picture below, row 16 is highlighted in red and cell D8 (on row 8) is the selected cell.
How can I freeze or setup a row header that does not move
To keep the top row or a set of rows frozen so they do not move as you scroll down use the freeze pane option.
