            </th>
        </tr>
    </thead>
    <thead>
        <tr>
            <th class="align-left">
                <div class="para">
                </div>
            </th>
            <th class="align-left">

There can be only one thead and tbody in a table. Both should be direct children of the <table> tag.

<table>
  <thead>
    <tr>
      <th align="right" colspan="4">
        <span class="font-style-bold">SCHEDULE OF RATES</span>
      </th>
    </tr>
    <tr>
      <th class="align-left">
        <div class="para">
        </div>
      </th>
      <th class="align-left">
        <div class="para">
        </div>
      </th>
      <th class="align-left">
        <div class="para">
          <span class="font-style-bold">Unit</span>
        </div>
      </th>
      <th class="align-left">
        <div class="para">
          <span class="font-style-bold">Rate $</span>
        </div>
      </th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td rowspan="align-left">
        <div class="para">
        </div>
      </td>
      <td rowspan="align-left">
        <div class="para">
          <span class="font-style-boldunderline">ROOFER</span>
        </div>
      </td>
      <td rowspan="align-left">
        <div class="para">
        </div>
      </td>
      <td rowspan="align-left">
        <div class="para">
        </div>
      </td>
    </tr>
  </tbody>
