What is the Purpose and Structure of CSS \'display: table-column\'?

CSS "display: table-column" Explained

In web development, the "display: table-column" property is often misunderstood. It's intended to work within the CSS table model, which is based on the HTML table model.

The CSS Table Model

A table in the CSS table model is divided into rows and columns, with cells occupying specific positions within rows. However, unlike HTML tables, "display: table-column" does not allow for content to be placed directly within columns.

Purpose of "display: table-column"

The main goal of "display: table-column" is to set attributes for table cells, similar to how the "display: table-cell" property does. For instance, it can define the background color of the first cell in each row.

How Columns are Structured

In HTML, columns are not containers for cells; cells are placed within rows. The same structure applies in the CSS table model. For example:

<code class="HTML"><table>
  <tr>
    <td>Column 1 Content</td>
    <td>Column 2 Content</td>
  </tr>
</table></code>

CSS Table Representation

To achieve a similar layout using CSS table properties:

<code class="CSS">.table {
  display: table;
}
.row {
  display: table-row;
}
.cell {
  display: table-cell;
}
.col-1 {
  display: table-column;
  background-color: green;
}
.col-2 {
  display: table-column;
}</code>

<code class="HTML"><div class="table">
  <div class="col-1"></div>
  <div class="col-2"></div>
  <div class="row">
    <div class="cell">Column 1 Content</div>
    <div class="cell">Column 2 Content</div>
  </div>
</div></code>

In this scenario, the "col-1" and "col-2" divs represent table columns but do not contain any direct content. The content is placed within the rows.
