Some basic documentation can be found here.

Can table-layout fixed be used with a middle column of auto width?

I’ve been reading several articles and questions related to the table-layout property on Stack Overflow, but I haven’t found a solution that addresses my specific issue. I’ve been stuck on this problem for a few hours, so I’m hoping someone can guide me in the right direction.

I have a table that handles a large amount of data and is usually much wider than the container. To allow horizontal scrolling, I’ve set the container to overflow-x: scroll. The client has the ability to define the widths of each column. However, a new requirement has emerged: the client wants the table to automatically adjust the column widths to the minimum necessary if a width is not explicitly defined.

I’ve come across suggestions in various posts that recommend leaving the last column to have an automatic width. However, in my case, I need the flexibility to set any column to have an auto width.

I’ve considered changing the table-layout property to auto, as I believe it might be the solution. However, when I make this change, I’m unable to set the width of any column individually; instead, the widths adjust equally for all columns.

Here’s a small snippet that illustrates the issue. The column with ### should have an auto width, but currently, it gets hidden behind col 4 when I attempt to do so.

.container {
  width: 400px;
  border: 1px solid red;
  overflow-x: scroll;
}

.container table {
  width: 100%;
  table-layout: fixed;
  text-align: left;
  border-collapse: collapse;
}

.container th,
.container td {
  border: 1px solid blue;
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
}
<div class="container">
  <table>
    <colgroup>
      <col style="width: 50px;">
      <col style="width: 300px;">
      <!-- <col style="width: 50px;"> -->
      <col style="width: auto;">
      <col style="width: 100px;">
    </colgroup>
    <thead>
      <tr>
        <th>Columna 1</th>
        <th>Columna 2</th>
        <th>###</th>
        <th>Columna 4</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>Contenido 1</td>
        <td>Contenido 2</td>
        <td>###</td>
        <td>Contenido 4</td>
      </tr>
      <tr>
        <td>Contenido 5</td>
        <td>Contenido 6</td>
        <td>###</td>
        <td>Contenido 8</td>
      </tr>
    </tbody>
  </table>

</div>

    So all you need to do is changing the required columns width to auto <col style="auto;"> and adding a class to ### elements <td class="hash">###</td> and as by CSS side you need to change the CSS code to:

    .container th,
.container td:not(.hash) {
  border: 1px solid blue;
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
}

    So it will hide all other fields but those that contains hash class

    table-layout: auto; – correct direction of thoughts. And in order to set a specific width for the cells, set them simultaneously min-width and max-width:

    * {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

.container {
  width: 400px;
  border: 1px solid red;
  overflow-x: scroll;
}
table {
  width: 100%;
  border-collapse: collapse;
}

td {
  border: 1px solid blue;
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
  width: 0;
  min-width: var(--width);
  max-width: var(--width);
}

td:nth-child(1) {
  --width: 50px;
}

td:nth-child(2) {
  --width: 300px;
}

td:nth-child(3) {
  --width: unset;
}

td:nth-child(4) {
  --width: 100px;
}
    <div class="container">
  <table>
    <thead>
      <tr>
        <td>Columna 1</td>
        <td>Columna 2</td>
        <td>###</td>
        <td>Columna 4</td>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>Contenido 1</td>
        <td>Contenido 2</td>
        <td>###</td>
        <td>Contenido 4</td>
      </tr>
      <tr>
        <td>Contenido 5</td>
        <td>Contenido 6</td>
        <td>###</td>
        <td>Contenido 8</td>
      </tr>
    </tbody>
  </table>
</div>
