Tables: Support for multiple <tbody>

Created by: ledermann

Because a <table> is allowed to contain multiple <tbody> to build groups of rows, it would be nice to style them with Bootstrap.

Example 1: Striped groups:

tbody:nth-child(odd) { background: #f5f5f5; }
tbody:nth-child(even) { background: #e5e5e5; }

Example 2: Placing a separator between groups:

tbody { border-top: 10px solid #ccc; }
tbody:first-of-type { border-top: 0; }

But both do not work nice with .striped-table. Any ideas?
