Header style in tables - Robohelp 2020 Update 6

If you modify the code in your topic and stylesheet you should be able to get it to work. 

As always, use a test project/topic in case something goes wrong. 🙂

You've converted the first row to a heading so your code should look something like this:

 <table border="1" cellpadding="1" cellspacing="1" class="Shaded" style="border-collapse:collapse; width:100%">
    <colgroup>
      <col style="width:16.67%" />
      <col style="width:16.67%" />
      <col style="width:16.67%" />
    </colgroup>
     <tbody>
      <tr>
        <th>Heading</th>
        <th>Heading</th>
        <th>Heading</th>
      </tr>
      <tr>
        <td>test</td>
        <td>test</td>
        <td>test</td>
      </tr>

You need to move the <tbody> tag underneath your first row, and add <thead></thead> around your first row. I've added some notes to highlight the changes, but don't include these notes in your page.

<table border="1" cellpadding="1" cellspacing="1" class="Shaded" style="border-collapse:collapse; width:100%">
    <colgroup>
      <col style="width:16.67%" />
      <col style="width:16.67%" />
      <col style="width:16.67%" />
    </colgroup>
     <thead> /*added thead here*/
      <tr>
        <th>Heading</th>
        <th>Heading</th>
        <th>Heading</th>
      </tr>
    </thead> /*added /thead here*/
    <tbody> /*moved tbody here*/
      <tr>
        <td>test</td>
        <td>test</td>
        <td>test</td>
      </tr>

If your header styling is now messed up you need to go into the stylesheet code to change the style for your header. It'll look something like this:

table.MyTableStyle tr:first-child td {
  color: white;
  background-color: green;
  font-weight: bold
}

Change table.MyTableStyle tr:first-child td to table.MyTableStyle thead th.

table.MyTableStyle thead th {
  color: white;
  background-color: green;
  font-weight: bold
}

See if that works for you.

I don't think that is supported in PDF or Word outputs. Word has that option to set within Word.

Never really played with table formatting, but I would suggest updating to Patch 7 first.
