You can filter rows from a table:

<table>
  <thead><tr><th><input _="on input
   show <tbody>tr/> in closest <table/>
     when its textContent.toLowerCase() contains my value.toLowerCase()
  "/></th></tr></thead>
  <tbody style="height:10em;display:block;overflow-y:scroll">
    <tr><td>Foo Bar</td><td>Item 1</td></tr>
    <tr><td>Boo Bar</td><td>Item 2</td></tr>
    <tr><td>Gru Bar</td><td>Item 3</td></tr>
    <tr><td>Zoo Bar</td><td>Item 4</td></tr>
    <tr><td>Foo Bar</td><td>Item 5</td></tr>
  </tbody>
</table>

Here we use the show command along with when and with clauses to filter rows. Note that we use a query selector to ensure we only perform operation over the body of the table instead of on the input. We set a static height for the <tbody> element and set scrollbars for overflow-y to avoid reflow for the rest of the page during filtering.
