When I edited an answer to add a second markdown table, both the first and second tables rendered correctly in preview, but the second table does not render. I've waited about 10 minutes in case there is some cache/refresh issue, and also tried both Chrome (87.0.4280.88 64-bit win10) and Firefox (84.0.1 64-bit win10) with equivalent result.

I think the actual problem is that the preview works even if there is no blank line before the table header row.

Simple table (looks good in preview) but no blank line before table header: | Question | Date Created | Date Closed | | -------- | ------------ | ----------- | | xxxxx | xxxxx | xxxxx | | xxxxx | xxxxx | xxxxx |

My earlier thought process is here, OK to stop reading at this point:

Both instances of this table in markdown look correct in the preview here on meta... let me see if they render correctly once posted...

After posting, both instances look incorrect. Is the table malformed?

Can it please be made so that the preview also doesn't render tables if there's no blank line between the table header and the line of text above it, so it matches the actual post rendering?

    There needs to be an empty line above the table header. Currently there’s the line “These have been dealt with by adding additional tags:” directly above it. – Sebastian Simon Jan 5 at 1:36
  • @user289905 want to make that an answer? I think you're right, I just now fixed up my original post. Leaving this here as a signpost for others. – MarkU Jan 5 at 1:39
  • Weird, I reported a bug here but in that case it was broken in preview but working after it was saved. – Kodos Johnson Jan 5 at 1:40

    This has already been reported here: New Feature: Table Support. Dang, @KodosJohnson beat me to it. – Sebastian Simon Jan 5 at 1:40
  • disregard my comment above, it is the same issue. – Kodos Johnson Jan 5 at 1:43

    Does this answer your question? Markdown preview doesn't match post – Kodos Johnson Jan 5 at 2:13

    @KodosJohnson Don't think that this is a duplicate of that. That one's a completely different bug, regarding line breaks after a table; this one is about line breaks before a table. While they may be the same cause, I'd leave those as two separate reports since they're two different bugs; if they turn out to be the same, an SE employee can close this. – Sonic the Curiouser Hedgehog Jan 5 at 2:14
