Table Alternate Rows
Many Drupal themes implement "zebra-striping", where table rows alternate background colours. This helps to improve the readability of tables by providing a visual queue to easily see which items are in the same row, even across a large table. Unfortunately, if tables are used within content, then it is unlikely that users will manually add the appropriate even / odd CSS classes to table rows. This module transparently adds those classes, without any intervention on the part of the user.
