Markdown Filter: Table is not extracted properly and is shown in rows.

Created by: deeagraw

This is extension of the bug #687

The table is defined as follows

| Hello | World |
|---|---|
| How | are you? |

While extracting and merging, the rows after table separator are not extracted properly table-extraction.png

The reason for the issue being a newline added after the table separator "|---|---|" in the merged file.
