sortable - a tiny, vanilla JS table sorter

Makes any table with class="sortable", er, sortable. That is the user can click on a table header and change the sorting of the table rows.

Just include the JavaScript and it will work. No function calls needed, all is done with an eventListener. (the CSS is not strictly needed, but makes it ~pretty and user friendly)

Factoids

• 900 bytes minified. (532 bytes gzipped)

• Works with JS/ajax generated tables.(due to the eventListener)

• Lightning fast. Huge tables will make it slow and may freeze the browser, especially for mobiles, so you know...

• Requires thead and tbody.

• cross browser, ie9+

• ~~eventListeners attached to the rows WILL be removed~~

• eventListeners are no longer removed! 😊

• NOT tested with React, Angular, Vue, etc.

• Works with Svelte!

• table > class="sortable asc" let's you sort ascending as default. Thanks Nikita Dunajevs!

• data-sort-alt in tbody > td allows for alternative sorting while holding shift or alt. Thanks wodny!

• data-sort-col in thead > th allows you to set which column should be sorted, in case you are using colspans, for instance. Thanks Nick Kocharhook!

• Elements inside th now works. Thanks mxve!

Demo

You can find a simple demo on https://tofsjonas.github.io/sortable/

An example

<table class="sortable">
  <thead>
    <tr>
      <th><span>Role</span></th>
      <th>Name</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Genius</td>
      <td>Rick</td>
    </tr>
    <tr>
      <td><a href="javascript:alert('Inline javascript works!');">Sidekick</a></td>
      <td>Morty</td>
    </tr>
  </tbody>
</table>
<link href="https://tofsjonas.github.io/sortable/sortable.css" rel="stylesheet" />
<script src="https://tofsjonas.github.io/sortable/sortable.js"></script>

(The span is just there to prove that elements inside th works)

Non-sortable field

...using class and css

If you wish to disable sorting for a specific field, the easiest way is to add a class to it, like so:

<tr>
  <th class="no-sort">Role</th>
  <th>Name</th>
</tr>

and then use css to block clicks. like so:

.sortable th.no-sort {
  pointer-events: none;
}

...using css only

This is a bit trickier, but it doesn't require any changes to the html, so I guess it could be worth it in some cases.

/* the first column in every sortable table should not be sortable*/
.sortable th:nth-child(1) {
  pointer-events: none;
}

/* the seventh column in the second .sortable table should not be sortable*/
.sortable:nth-of-type(2) th:nth-child(7) {
  pointer-events: none;
}

td > data-sort

Using the data-sort attribute in tbody > td you can have one visible value and one sortable value. This is useful in case you have for instance sizes like kb, Mb, GB, etc.

<table class="sortable">
  <thead>
    <tr>
      <th>Movie Name</th>
      <th>Size</th>
      <th>Release date</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Zack Snyder's Justice League</td>
      <td data-sort="943718400">900MB</td>
      <td data-sort="20210318">03/18/2021</td>
    </tr>
    <tr>
      <td>The Sound of Music</td>
      <td data-sort="1610612736">1.5GB</td>
      <td data-sort="19651209">12/09/1965</td>
    </tr>
  </tbody>
</table>

td > data-sort-alt

If you click on a table header while holding shift or alt an alternative data-sort-alt attribute will override data-sort.

<table class="sortable">
  <thead>
    <tr>
      <th>Movie Name</th>
      <th>Size</th>
      <th>Release date</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Something</td>
      <td data-sort-alt="c" data-sort="a">A</td>
      <td data-sort-alt="b" data-sort="c">B</td>
      <td data-sort-alt="a" data-sort="b">C</td>
    </tr>
    <tr>
      <td>Something else</td>
      <td data-sort-alt="e" data-sort="f">D</td>
      <td data-sort-alt="f" data-sort="e">E</td>
      <td data-sort-alt="d" data-sort="d">F</td>
    </tr>
  </tbody>
</table>

th > data-sort-col

Using the data-sort-col attribute in thead > th, you can sort on a different column than the one that was clicked. For instance if you want to have colspans. Like so:

<thead>
  <tr>
    <th></th>
    <th>Category</th>
    <th class="show_name">Show</th>
    <th colspan="2">Overall</th>
    <th colspan="2" data-sort-col="5">On Our Dates</th>
    <th data-sort-col="7">First Sold Out</th>
  </tr>
</thead>
<tbody>
  <tr>
    <td class="tags">&nbsp;</td>
    <td class="category">Comedy</td>
    <td class="show_name">Show 1</td>
    <td class="ratio all" data-sort="72">18/25</td>
    <td class="pct all">72%</td>
    <td class="ratio ours" data-sort="75">3/4</td>
    <td class="pct ours">75%</td>
    <td>2022-07-30</td>
  </tr>
  ...
</tbody>

Ascending sort

By adding asc to table, the default sorting direction will be ascending instead of descending

<table class="sortable asc">
  <thead>
    ...
  </thead>
  <tbody>
    ...
  </tbody>
</table>
