Zebra Striped Table

If you have a long and wide table, it can be hard to follow the lines with your eyes. Therefore tables are often made zebra striped with a different colour for the odd or even lines.
To add rows to the table just copy one of the existent <tr>...</tr> with everything between those tags, as many times as needed. You don't have to worry about the colouring of lines, because the styling will automatically give the different colour to all even lines. Instead of 'even' one might just as well choose 'odd'.
