A guide to adjusting the width without affecting the td element

Currently, I am facing a challenge while coding in HTML. I am trying to create a table with a header (time range) that fits on a single line without affecting the width of the td elements. Below is the code snippet:

<table style="border:1px solid #8c8c8c;width:100%;border-collapse:collapse;margin-bottom:1.5em">
  <thead>
    <tr style="border-bottom:1px solid black;background-color:#e9e9e9;font-size:16px">
      <th width="24%">
        <div style="width:auto">10:35PM - 11:05PM (30 MIN)</div>
      </th>
      <th style="text-align:right;padding-right:1em;" height="40px;">John Williams</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td valign="baseline" style="width:15%;padding-left:0.5em;">
        <div style="line-height:2em;font-weight:bold"> Topic:</div>
      </td>
      <td valign="baseline">
        <div>Resume Review</div>
      </td>
    </tr>
    <tr>
      <td valign="baseline" style="width:15%;padding-left:0.5em">
        <div style="line-height:2em;font-weight:bold">Phone:</div>
      </td>
      <td valign="baseline">123445567</td>
    </tr>
    <tr>
      <td valign="baseline" style="width:15%;padding-left:0.5em">
        <div style="line-height:2em;font-weight:bold">Email:</div>
      </td>
      <td valign="baseline"><a href="mailto:<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="0d475849545f42495f444a58485738353e4d4a444b405845232e2220">[email protected]</a>" target="_blank"><a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6e24491510151456213c36383c25294b262a28">[email protected]</a></a></td>
    </tr>
    <tr>
      <td valign="baseline">
        <div style="line-height:2em;width:auto;font-weight:bold">Student notes:</div>
      </td>
      <td valign="baseline"> some junk test text</td>
    </tr>
  </tbody>
</table>

Note: It is essential to resolve this issue without the use of an external CSS file. Any suggestions on how to approach this?

Answer №1

If you want the first cells to have different widths, they must span different numbers of columns; otherwise, they will only fill one column.

For example, if you have a 2-column table, you can use the `colspan` attribute to turn it into a 3-column table.

In the `thead` section, you can achieve this by using `th 24% use space left `, creating 3 columns with the first cell spanning through 2 columns.

Similarly, in the `tbody` section, `15% space left` will also create 3 columns.

The second column will be 24% - 15% = 9%, which will be utilized by the cell that spans through 2 columns.

This is the theory in action: 

<table style="border:1px solid #8c8c8c;width:100%; border-collapse:collapse;margin-bottom:1.5em">
  <thead>
    <tr style="border-bottom:1px solid black;background-color:#e9e9e9;font-size:16px">
      <th width="24%" colspan="2">
        <div style="width:auto">10:35PM - 11:05PM (30 MIN)</div>
      </th>
      <th style="text-align:right;padding-right:1em;margin-right:1em;" height="40px;">John Williams</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td valign="baseline" style="width:15%; padding-left:0.5em;">
        <div style="line-height:2em;font-weight:bold"> Topic:</div>
      </td>
      <td valign="baseline" colspan="2">
        <div>Resume Review</div>
      </td>
    </tr>
    <tr>
      <td valign="baseline" style="width:15%; padding-left:0.5em">
        <div style="line-height:2em;font-weight:bold">Phone:</div>
      </td>
      <td valign="baseline" colspan="2">123445567</td>
    </tr>
    <tr>
      <td valign="baseline" style="width:15%;padding-left:0.5em">
        <div style="line-height:2em;font-weight:bold">Email:</div>
      </td>
      <td valign="baseline" colspan="2"><a href="mailto:<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="652f30213c372a21372c2230203f505d56252228242c294b262a28">[email protected]</a>" target="_blank"><a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2b617c424747424a6b6c666a626705686466">[email protected]</a></a></td>
    </tr>
    <tr>
      <td valign="baseline">
        <div style="line-height:2em;width:auto;font-weight:bold">Student notes:</div>
      </td>
      <td valign="baseline" colspan="2"> some junk test text</td>
    </tr>
