Hi, I'm experiencing an issue where tables written in MDX are not rendering correctly. Other Markdown elements like headings and paragraphs work fine, but tables don't appear at all in the rendered output.

Here's a simple example that doesn't work:

| First Header  | Second Header |
| ------------- | ------------- |
| Content Cell  | Content Cell  |
| Content Cell  | Content Cell  |

Is there something I'm missing in the configuration, or could this be a bug?

For reference, this is my Next.js config:

import createMDX from '@next/mdx';
import type { NextConfig } from 'next';

const nextConfig: NextConfig = {
  pageExtensions: ['mdx', 'ts', 'tsx'],
  experimental: {
    mdxRs: true,
  },
};

const withMDX = createMDX({});

export default withMDX(nextConfig);
