Mark-down tables fail to display on the English Language Learners Stack Exchange

Question

I was trying to answer a question on ELL.

I tried to draw a table:

| A header | Another header |
| -------- | -------------- |
| First    | row            |
| Second   | row            |

There is a previewer which displays what one's answer will look like before clicking the Post Your Answer button.

The previewer does not display a table, instead we have:

Answer 1

A header	Another header
First	row
Second	row

^That's a table at the top of the edit window^

This is a table with no blank line of text before it: | A header | Another header | | -------- | -------------- | | First | row | | Second | row |

This is a table with a blank line of text before it:

A header	Another header
First	row
Second	row

All of these look like words with no formatting in the preview window:

So, it seems ell.meta.stackexchange.com has different problems with previewing table formatting than meta.stackexchange.com does, and the same problems with displaying tables once it's submitted.

Answer 2

As you can see at Meta Stack Exchange there have been quite a few reported bugs with table preview, Known issues: if the table contains any tab characters it will render incorrectly. There must be a blank line before and after any table.
