Tables indented by double tabs do not render properly

[spencer246]

Version: Markdown-it v12.0.0

Description

Consider the following Markdown source: a table inside a nested list. Each line of the table is indented by two consecutive tabs.

- Level 1

	- Level 2

		| Column 1 | Column 2 |
		| -------- | -------- |
		| abcdefgh | ijklmnop |

What is expected (Github's implementation)

• Level 1

  • Level 2

    Column 1	Column 2
    abcdefgh	ijklmnop

What actually happens

It seems that the first 4 characters of each line after the tabs (| Co, | ab) is removed.

Discussions

According to the GFM spec, "in contexts where whitespace helps to define block structure, tabs behave as if they were replaced by spaces with a tab stop of 4 characters."

If every tab is replaced with 4 whitespaces, Markdown-it correctly renders the table.
