# Network-wide feature request to support TeX in tables

Many of us here frequently use MathJax, whether for this site or another site on the SE Network. Recently SE added support for tables, but ignored the needs of the TeX community, who wish to be able to type TeX symbols/formulas/etc. as well.

### This is the feature request on Meta.SE, to support MathJax in tables.

Here's some network-wide examples where such support would be needed (please add anymore if you're aware of any!):

Update: Since creating this feature request on Meta.SE, we can now see that MathJax works in the tables, for most examples:

Limit $$\lim\limits_{x\to\infty} f(x)$$
Matrix $$\begin{pmatrix}1&2\\0&1\end{pmatrix}$$
Cardinals $$\mathfrak c^{\aleph_0}=\mathfrak c$$
Equation with a tag $$\begin{equation} x^2+y^2=z^2 \tag{1} \end{equation}$$
Centered formula $$F_{n+2}=F_{n+1}+F_n$$
Is the right-side ruined just because there's Mathjax in the header? $$\int e^x=f(u)n$$
$$\int e^x = f(u)n$$
• Ok, but we can already make tables directly in MathJax. Do we really need to be able to put MathJax inside Markdown tables? Dec 6, 2020 at 17:58
• @PM2Ring The 4 examples I gave do exactly what you suggested, but needed to make the entire table in MathJax just for a tiny number of symbols such as $^3\Sigma$ for "triplet sigma" states. We most certainly 100% need to be able to put MathJax in Markdown tables. Dec 6, 2020 at 18:01

Table support Working $$\Large\checkmark$$
MathJax support in tables test: $$\int e^x dx = f(x)$$ -- yes, it works! $$\Large\checkmark$$
Feature requests for MathJax support Successful! $$\Large\checkmark$$ (no longer needed)
• Yes I'll give some examples where MathJax is needed in the header, later once I've finished some other things and acquired time to go and take a screenshot of those tables. However at the moment the highest voted feature-request on the Meta.SE post is to allow lowercase letters in the headers (currently the headers have to be in all caps, unbelievable!). One way around that is to use $\textrm{Lower case header}$ but that messes up the equations that are in that column. These might be "edge cases" but SE can take ages to fix bugs, so it might be good to get them all fixed early while attention. Dec 10, 2020 at 22:46
