Each sheet can hold hundreds, if not thousands, of rows and columns. When scrolling through data, it is important to be able to see the table headers when viewing data at any point in the sheet. You can freeze a row(s) or column(s) to hold it in place while scrolling.
To freeze a row or column:
Move the cursor to the top left corner of the sheet.
Click and grab the thick grey line of either the row or column.
Drag to the row or column that you would like to freeze.
