Oat Table

Semantic table enhancement for Oat UI. Sort, filter, and select rows without turning tables into a framework widget.

Oat Table is a small, zero-runtime-dependency extension for Oat. It keeps the native <table> as the source of truth and adds progressive behavior around it:

• sortable columns via th[data-sort]
• client-side filtering via [data-table-filter]
• row selection via native checkboxes
• empty and status output helpers
• Oat theme variables and component layers

The table remains readable and usable without JavaScript. With JavaScript enabled, <ot-table> wires up keyboard-friendly sort buttons, ARIA sort state, filter state, selection state, and events.

Install

With npm:

npm install @globus.studio/oat-table

import '@globus.studio/oat-table/css';

Basic Usage

<ot-table>
  <form data-table-toolbar role="search">
    <label>
      Search
      <input type="search" data-table-filter placeholder="Filter rows">
    </label>
    <output data-table-status aria-live="polite"></output>
  </form>




    <table>
      <thead>
        <tr>
          <th scope="col" data-sort>Name</th>
          <th scope="col" data-sort="number">Open tickets</th>
          <th scope="col" data-sort="date">Last seen</th>
        </tr>
      </thead>
      <tbody>
        <tr>
          <td>Ada Lovelace</td>
          <td>4</td>
          <td><time datetime="2026-05-15">15 May 2026</time></td>
        </tr>
        <tr>
          <td>Grace Hopper</td>
          <td>12</td>
          <td><time datetime="2026-05-10">10 May 2026</time></td>
        </tr>
      </tbody>
    </table>



</ot-table>

Sort

Add data-sort to a header cell. Oat Table wraps the header content in a plain button and updates aria-sort on the active header.

<th scope="col" data-sort>Name</th>
<th scope="col" data-sort="number">Revenue</th>
<th scope="col" data-sort="date">Created</th>

Supported sort types are text, number, date, and auto. Empty data-sort defaults to text.

Use data-sort-value on a cell when the visible text is formatted:

<td data-sort-value="42128">$42,128</td>

Filter

Place an input with data-table-filter anywhere inside <ot-table>.

<input type="search" data-table-filter placeholder="Filter rows">
<output data-table-status aria-live="polite"></output>

Filtering matches the row text. Use data-filter-text on a row to provide a custom searchable string.

<tr data-filter-text="ada admin active london">
  ...
</tr>

Set a custom empty message on the wrapper:

<ot-table empty-text="No customers match this search">

Select Rows

Selection uses native checkboxes. This keeps forms and accessibility straightforward.

<th scope="col"><input type="checkbox" data-table-select-all aria-label="Select all visible rows"></th>

<td>
  <input type="checkbox" data-table-select-row value="customer-1" aria-label="Select Ada Lovelace">
</td>

Add an optional selected count output:

<output data-table-selected aria-live="polite"></output>

The select-all checkbox affects visible rows only, which makes it work naturally with filtering.

Events

const table = document.querySelector('ot-table');

  console.log(event.detail.column, event.detail.direction);
});

table.addEventListener('ot-table-filter', (event) => {
  console.log(event.detail.query, event.detail.visibleRows.length);
});

table.addEventListener('ot-table-select', (event) => {
