Hello raekertim.

Thank you for your purchase.

I am sorry, but we haven't tried using MathML in wpDataTables, but from a brief test, it looks like it can't be used in the tables.

I've tried the simplest equation example, but unfortunately it didn't work:

<mrow>
  <mrow>
        <msup> <mi>x</mi> <mn>2</mn> </msup> <mo>+</mo>
            <mrow>
              <mn>4</mn>
              <mo>⁢</mo>
              <mi>x</mi>
            </mrow>
    <mo>+</mo>
    <mn>4</mn>
  </mrow>
    <mo>=</mo>
    <mn>0</mn>
</mrow>

Have you checked if there are some MathML plugins that could generate a shortcode which you can paste into a cell? I don't guarantee that'll work either, but since wpDataTables supports shortcodes in cells, it may be a possibility.

Unfortunately the issues like conflicts with third party plugins or themes are always possible due to the nature of WP.

Also, please note that MathML is currently supported only on Firefox browsers, so I don't know how useful it'd be even if we somehow got it to display in our tables. Here's an example in Chrome:

And the same page in Firefox:

Best regards.
