Render latex in table

# Description

I want to use asciidoctor table to record some formulas in probability theory, some formulas involves latex.

```
|===
| distribution | parameter | probability distribution | E(x) | D(x)

| binominal distribution
| n \geqslant 1

0 < p < 1
| P{X=k} = \binom{n}{k} p^k (1-p)^{n-k}
| np
| np(1-p)

| poisson distribution
| \lambda > 0
| P{X=k} = \frac{\lambda^k e^{-\lambda}}{k!}, k=0,1 ...
| \lambda
| \lambda

| uniform distribution
| a < b
|
| \frac{a+b}{2}
| \frac{(b-a)^2}{12}

| exponential distribution
| \lambda > 0
|
| \frac{1}{\lambda}
| \frac{1}{\lambda^2}


| normal distribution
| \mu, \sigma > 0
|
| \mu
| \sigma^2

|===
```

# First try failed

I go through the Asciidoctor User Manual, and decide to use stem block

```
= Render formula in table
:stem: latexmath

[stem]
++++
put that table here
++++
```

But it doesn't render table.

# Second try success

Then I try to use inline latexmath macro syntax like `latexmath:[C = \alpha + \beta Y^{\gamma} + \epsilon]`

```
= Render formula in table
:stem: latexmath

[stem]
++++
|===
| distribution | parameter | probability distribution | E(x) | D(x)

| binominal distribution
| n \geqslant 1

0 < p < 1
| latexmath:[P{X=k} = \binom{n}{k} p^k (1-p)^{n-k}]
| np
| np(1-p)

|===
++++
```

It works, but I need to add inline latexmath macro syntax for every formula.

# Better way?

I want to know if there is some easier ways to do that?

Adding a latexmath:[] for every formula is the only way it will work AFAIK. This allows you to choose for each cell if it is math or text, and you can even mix math and text within a cell.
