When you are working with lot of data in a Spreadsheet, the headings would disappear when you start scrolling down the rows. Google Docs Spreadsheet provides users with the option for keeping the headings always visible even when you scroll down the Sheet. This can be done by using the menu option available as part of the View menu. To explain, let us take the take following sample data
Now when the users scroll down below Row no 26, the heading rows would disappear as shown below.
And it will be difficult for the users to find out the column under which the values fall. This problem can be addressed using the Freeze rows feature. Navigate to View menu then Freeze rows and select Freeze 1 row menu option.
This would always Keep the heading rows always visible in a Google Docs Spreadsheet.
