Question

What is the best way to prevent the headers row from being affected by certain functions that toggle the visibility of table rows

I came across a fascinating script that breaks up a table into "pages" on the same page. I'm intrigued by how to exclude the header row so that it always remains visible, and ensure that the new tables inherit the style of the original complete table. It would be great to have an option to disable the splitting if needed (though not essential). The page and table are generated dynamically from another file, and I also intend to allow users to add their own rows in the future.

Here's a snippet with added lines:

<tbody id="some_id"><tr id="header" class="header">
<th>head1</th>
<th>head2</th>
<th>head3</th>
</tr>

 // Code continues...

Initially, I removed the test2 table as I only require one set of buttons. However, I am unsure on how to retain both the first row and the styling when splitting the tables this way. Perhaps there is a simpler way to split them without creating new pages, keeping everything in one file for convenience and offline usage.

Exploring how to manipulate such functions will definitely benefit me in the future.

Answer №1

To improve your table structure, consider wrapping the header in <thead> and the data rows in <tbody>. This will make your HTML cleaner and more semantic:

{
const rows = [...document.getElementById('table').rows].slice(1);
rows[0].cells[0].textContent = 'Test';
}
{
const rows = document.querySelectorAll('#table2>tbody>tr');
rows[0].cells[0].textContent = 'Test';
}

<table id="table">
  <tr id="#header"><th>Header</th></tr>
  <tr><td>Data</td></tr>
</table>

<table id="table2">
  <thead>
    <tr id="#header"><th>Header</th></tr>
  </thead>
  <tbody>
    <tr><td>Data</td></tr>
  </tbody>
</table>
