HTML Table Math

Render LaTeX math inside raw HTML table cells for Obsidian.

Obsidian renders $...$ math in regular markdown, but not inside raw HTML tables. This plugin fills that gap: math in <table> cells is rendered with MathJax in both Reading View and Live Preview.

Usage

Write math as you normally would, inside the td / th cells of a raw HTML table:

<table>
  <tr>
    <th>Notation</th>
    <th>Meaning</th>
  </tr>
  <tr>
    <td>$\operatorname{span}(\mathbf{x})$</td>
    <td>$$E = mc^2$$</td>
  </tr>
</table>

Supported delimiters (matching Obsidian's own math):

• $ ... $ — inline math
• $$ ... $$ — display math
• \$ — a literal dollar sign

Everything else in the cell — plain text, escaped $, unbalanced $ — is left exactly as-is.

Settings

Setting	Description
Enable rendering	Master switch for the plugin.
Live Preview	Whether math is rendered in Live Preview as well as Reading View.
On render error	What to show when a formula fails to render: keep the raw LaTeX, or MathJax's error output.

Changes to the settings apply immediately to already-open notes — no reload required.

Requirements

• Obsidian 1.13.0 or newer (uses the declarative settings API)
