Table with embbed images will be converted to a looooooong head table with many blanks

Bug found in version: 2.1.0

Input:
`

Table with images

name

pic

jack

Output(Hard to show, so I use the screenshot):


This long head table in markdown will make some of the markdown editor stuck, which may lead a crash.

Wish it to be fixed, thanks.

Reproduce the conversion with the provided HTML table containing an embedded base64 image and compare the generated Markdown with the screenshot. Trace the table conversion entry point used by the CLI; done means the image does not produce a very long header with blank cells and the resulting Markdown no longer causes an editor to become stuck or crash.
