ADF UI - How to include Row Header for af:table?

If you're using af:table and row selection is enabled for the table, a must for the table is 'Row Header'. Row header enables the user to select a single row from the table. To add a row header to the table, just add a blank column as the first column and specify width="5", minimumWidth="5" and rowHeader="true" and specify align="right". Don't include any field inside this row header column.

Below is the code for row header. You can copy-paste this code as a first column in the table and that's it. You're done!

<af:column id="c4" rowHeader="true" width="5" minimumWidth="5"
                     align="right"/>
