-KaTeX also supports:
-* `darray`, `dcases`, and `drcases`, which render in `displaystyle`
-* `align*`, `alignat*`, `gather*`, and `equation*`, which omit equation numbers
-* `aligned`, `alignedat`, and `gathered`, which LaTeX will render while in math mode
-
-Environments `align`, `alignat`, `CD`, `equation`, and `gather` (and their starred versions) may be called from display mode. This usually means that they may be called from within `$$…$$` delimiters or `\[…\]` delimiters. They may not be called from within `$…$` or `\(…\)` delimiters. In the KaTeX auto-render extension, as in LaTeX, these environments are themselves are a way to change from text mode to math display mode, and `\[…\]` delimiters are not necessary.
-
-And KaTeX supports `matrix*`, `pmatrix*`, `bmatrix*`, `Bmatrix*`, `vmatrix*`, and `Vmatrix*`, which take an optional argument to set column alignment, as in `\begin{matrix}[1]`, `\begin{matrix}[c]`, or `\begin{matrix}[r]`.
-
Acceptable line separators include: `\\`, `\cr`, `\\[distance]`, and `\cr[distance]`. *Distance* can be written with any of the [KaTeX units](#units).
The `{array}` environment supports `|` and `:` vertical separators.
