+### `theme_mitex()`
+
+This theme was written by Kazuharu Yanagimoto. Thanks for your contribution!
+
+The [MiTeX project](https://typst.app/universe/package/mitex/) aims to bring LaTeX support to Typst documents. This theme replace every instance of matching pairs of dollars signs `$..$`  by a MiTeX function call: `#mitex(...)`. This allows you to use LaTeX math in Typst documents.
+
+Warning: The substitution code is very simple and it may not work properly when there are unmatched `$` symbols in the document.
+
+```r
+theme_mitex <- function(x, ...) {
+    fn <- function(table) {
+        if (isTRUE(table@output == "typst")) {
+          table@table_string <- gsub("\\$(.*?)\\$", "#mitex(`\\1`)", table@table_string)
+        }
+        return(table)
+    }
+    x <- style_tt(x, finalize = fn)
+    x <- theme_tt(x, theme = "default")
+    return(x)
+}
+```
