I am trying to convert HTML pages from our Confluence Wiki to Github Flavored Markdown for the Github Wiki.

I want to remove all formatting to get a "vanilla" Markdown output without embedded HTML. I settled on this command for the moment:

```sh
pandoc failing_table_tidy_reduced.html -f html-native_divs-native_spans -t gfm-raw_html -o failing_table_tidy_reduced.md
```

**(The contents of `failing_table_tidy_reduced.html` are pasted below.)**

The Markdown output is OK for the most part, except that the table headers are systematically broken. I get this for the example file that is pasted below:

```md
| | | |
|------------------------------------------------|-----------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------|
| Step 1: Select to open image as virtual stack. | Step 2: Select image folder and open dataset. | Step 3: View with opened image stack. Use the slider of in the phase contrast histogram (top) to adjust image saturation for better channel visibility. |
| ![](attachments/314948158/314950704.png) | ![](attachments/314948158/314950710.png) | ![](attachments/314948158/314950785.png) |
```

Whereas I expect the text (ie. "Step N: ...") to be in the table header, like so:

```md
| Step 1: Select to open image as virtual stack. | Step 2: Select image folder and open dataset. | Step 3: View with opened image stack. Use the slider of in the phase contrast histogram (top) to adjust image saturation for better channel visibility. |
|------------------------------------------------|-----------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------|
| ![](attachments/314948158/314950704.png) | ![](attachments/314948158/314950710.png) | ![](attachments/314948158/314950785.png) |
```

What am I doing wrong?
