What are the steps to add 8 columns to the second row in my table?

this is an example of HTML code that showcases a table structure with multiple rows and columns. You can view the full code snippet here.

The table includes different sections, such as section1, section2, section3, and section4 in the first row (tr). In the subsequent rows, there are additional items needed to be displayed, with each item having its own unique identifier.

<table id="main_table">
    <thead>
        <tr class="firstline">
            <th>Column1</th>
            <th>Column2</th>
            <th>Column3</th>
            <th>Column4</th>
        </tr>
    </thead>

...

If you're interested in how these different sections interact dynamically using jQuery, here's a sample of the JavaScript code:

jQuery(function($) {


    $("#polls").on("click", ".flip", function() {

        $(this)

            .closest('tbody')
            .next('.section')
            .toggle('fast');
    });
});

Answer №1

To apply the attribute colspan="2" to all cells within rows containing four cells.

Answer №2

Twice the number of TDs in the second row; also, include a colspan="2" on each TH to indicate it should span 2 columns

<thead>
    <tr class="firstline">
        <th colspan="2">Column1</th>
        <th colspan="2">Column2</th>
        <th colspan="2">Column3</th>
        <th colspan="2">Column4</th>
    </tr>
</thead>
<tbody>
    <tr style="width:1002px; background-color:green; color:white">
        <td  class="flip"> Section 1 </td>
         <td  class="flip"> Section 2 </td>
         <td  class="flip"> Section 3 </td>
         <td  class="flip"> Section 4 </td>
         <td  class="flip"> Section 5 </td>
         <td  class="flip"> Section 6 </td>
         <td  class="flip"> Section 7 </td>
         <td  class="flip"> Section 8 </td>
    </tr>
</tbody>

Answer №3

Easy: Change all td elements within columns of 4 to have a colspan="2"
