Xenforo standard css layout classes

[XFFA.IR Bot]

I'm building a html table for my add-on, and i'd like to know if there is some standard css layout for it such as the code below for 'divs':

Code:

<div class="block-container">
    <div class="block-body">
      <div class="block-row">

Something similar for table? Where can I find a list of available css classes from Xenforo?

Code:

<table>
    <thead>
      <tr>
        <th>
