To specify the horizontal text alignment of the columns, you need to assign three letters to the align attribute. Each letter represents the horizontal text alignment of a column. The letter can be L, C, or R. For example, if you want the following settings to be applied to your table:
First table column — Left-aligned
Second table column — Center-aligned
Third table column — Right-aligned
Then you should set the value of the align attribute to LCR.
