How to Select Specific Columns in a Table Using CSS `nth-child` Selectors?

CSS Selectors for nth Range

To select specific columns in a table, utilize the nth-child CSS selector. The provided selector, '.myTableRow td:nth-child(?)', targets table data cells (td) based on their position in the parent table row. However, the question mark placeholder needs replacing with a range.

nth-Child Range Selection

To select columns 2 through 4, employ either of these approaches:

Option 1:

<code class="css">.myTableRow td:nth-child(n+2):nth-child(-n+4){
  background-color: #FFFFCC;
}</code>

This syntax ensures selection of cells starting from the 2nd position (n 2) and up to the 4th position (-n 4).

Option 2 (Clearer Syntax):

<code class="css">.myTableRow td:nth-child(2):nth-child(4){
  background-color: #FFFFCC;
}</code>

This alternative provides a more explicit range specification, explicitly identifying columns 2 and 4. It eliminates the need to calculate the total number of columns.

nth-Child Syntax Explanation:

• ':nth-child(n X)' targets elements from the 'Xth' position onward.
• ':nth-child(-n X)' targets elements up to the 'Xth' position.

Example:

Consider the following HTML:

<code class="html"><table class="myTable">
  <tr>
    <td>Item 1</td>
    <td>Item 2</td>
    <td>Item 3</td>
  </tr>
</table></code>

Applying the selector '.myTable tr:nth-child(2)' would highlight the second row in the table.
