Hello. Tables aren’t part of the original Markdown spec so different systems implemented their own syntax. For the TensorFlow docs, we optimize viewing for the webpage and use GitHub as a preview for convenience—but there are some Markdown discrepancies. Some pages can also be viewed in Colab.
Since the webpage 3 renders correctly, please use that Markdown syntax for the table on that page. And, depending on the data and format, might just prefer a regular ole’ HTML table that renders everywhere. We use those, too.
