I have a table with four columns and two rows, as follows:

<table>
<tr>
    <td> A </td>
    <td> B </td>
    <td> C </td>
    <td> D </td>
</tr>
<tr>
    <td> E </td>
    <td> F </td>
    <td> G </td>
    <td> H </td>
</tr>
</table>

Using a media query, such as @media (max-width: 800px), I want to restructure this table to instead have two columns and four rows, e.g:

<table>
<tr>
    <td> A </td>
    <td> B </td>
</tr>
<tr>
    <td> C </td>
    <td> D </td>
</tr>
<tr>
    <td> E </td>
    <td> F </td>
</tr>
<tr>
    <td> G </td>
    <td> H </td>
</tr>
</table>

Is this possible? Solutions in JavaScript are also welcome if, which I assume to be the case, this cannot be done with mere CSS.

Pure CSS

Changing the appearance using floats and nth-child.

td { float:left; display:inline-block; }
td:nth-child(3) {
  clear:both;
}

JavaScript

Looping through all applicable columns and use the modulus operator to determine where to split out into new rows.

var table = document.getElementsByTagName('table')[0],
  columns = Array.prototype.slice.call(document.getElementsByTagName('td')),
  newTable = document.createElement('table'), html;

columns.forEach(function(next, idx) {
  if (idx % 2 === 0 || idx === 0) {
    html += '<tr>' + next.outerHTML;
    return;
  }
  html += next.outerHTML + '</tr>';
});

newTable.innerHTML = html;
table.replaceWith(newTable);
