jquery - Fixed table header with dynamic content?

Question

I've found several solutions for a fixed header, but none of them will fix my problem.

I have a table, styled with jQuery mobile (Responsive table). This table is dynamically filled with a .append. The columns don't have a fixed width, they vary. Is there a way, to fix the header of the table, so that I am able to scroll through the table body with the header always showing at the top, but without the use of multiple tables.

Summary:

I would like to have a single table with a fixed header.

I'm amazed that there is no standard for this, as I assume that this is something most webdevs can use. Please, correct me if I'm wrong.

Thank you in advance!

Edit:

Example:

<table id="my_id" data-role="table" class="ui-body-d ui-shadow table-stripe
 ui-responsive">
    <thead id="must_be_static">
       <tr>
          <th>This guy should be static</th>
          <th>This guy should be static</th>
          <th>This guy should be static</th>
          <th>This guy should be static</th>
          <th>This guy should be static</th>
       </tr>
    </thead>
    <tbody id="id_for_content">
       <tr>
          <td>Dynamic content</td>
          <td>Dynamic content</td>
          <td>Dynamic content</td>
          <td>Dynamic content</td>
          <td>Dynamic content</td>
       </tr>
    </tbody>
    <tfoot>
       <tr>
          <td>Foot</td>
          <td>Foot</td>
          <td>Foot</td>
          <td>Foot</td>
          <td>Foot</td>
       </tr>
    </tfoot>
</table>

你看起来像这样吗::

    <table border="1">
  <thead>
    <tr>
      <th class="month">Month</th>
      <th class="saving">Savings</th>
    </tr>
  </thead>
  <tfoot>
    <tr>
      <td>Sum</td>
      <td>$180</td>
    </tr>
  </tfoot>
  <tbody>
    <tr>
      <td>February</td>
      <td>$80</td>
    </tr>
      <tr>
      <td>January</td>
      <td>$100</td>
    </tr>
  </tbody>
</table>

你能举个例子来说明你正在尝试做什么吗？因为听起来你有一个 css 问题而不是 jquery 问题。
