Advanced HTML Table Layouts in GitHub Markdown (2 & 3 Columns)

Supported HTML Tags in GitHub Markdown

GitHub's HTML sanitizer strips inline CSS style tags, class names, and JavaScript. However, it permits standard table attributes:

align="left|center|right" — Align text or images within a cell.
width="50%" — Set relative column widths so cells scale across viewports.
valign="top|middle|bottom" — Vertically align content within a cell.
border="0" — Remove visible borders for clean grid designs.

2-Column Layout Example

<table border="0">
  <tr>
    <td width="50%" valign="top">
      <h3>🚀 Bio</h3>
      <p>Full-stack developer building developer tools.</p>
    </td>
    <td width="50%" valign="top">
      <h3>⚡ Stats</h3>
      <img src="stats-card-url" width="100%" />
    </td>
  </tr>
</table>
