+## Tables
+
+The `mdxishTables` transformer converts JSX Table elements to markdown table nodes and re-parses markdown content in table cells.
+
+The old MDX pipeline relies on `remarkMdx` to convert the table and its markdown content into MDX JSX elements. Since mdxish does not use `remarkMdx`, we have to do it manually. The workaround is to parse cell contents through `remarkParse` and `remarkGfm` to convert them to MDX JSX elements.
+
+### Example
+
+```html
+

+  
+    
+      
+      
+    
+  
+  
+    
+      
+      
+    
+    
+      
+      
+    
+  
+
TypeExample
Bold**Bold text**
Italic*Italic text*

+```
+
+This gets converted to a markdown `table` node where the cell containing `**Bold text**` is parsed into a `strong` element with a text node containing "Bold text".

 ## HTMLBlocks
 
 The `mdxishHtmlBlocks` transformer converts `{`...`}` syntax to `html-block` MDAST nodes. The HTML string is stored in `data.hProperties.html` and passed to the React `HTMLBlock` component via the `html` prop during HAST→React conversion, ensuring compatibility with both the `mdxish` and `compile`+`run` pipelines.
+
+The transformer handles nested template literals with code fences (e.g., `{`
```javascript\nconst x = 1;\n```
`}`), preserving newlines and correctly reconstructing triple backticks that may be consumed by the markdown parser. The `formatHTML` utility processes the content to unescape backticks, convert `\n` sequences to actual newlines, and fix cases where the parser consumed backticks from code fences.
