More ergonomic table-input HTML

[fregante]

I think this generates a slightly more usable HTML:

• if there's only one column, print one HTML line per table row
• reduce the indentation because it can issues in Markdown, like:

<table>
<tr>
	<td> 

	<td>

<tr>
	<td>

	<td>

</table>

Causes:

<td>

<td>

The extra line breaks are used sometimes to re-enable markdown parsing in the table, like:

<table>
<tr>
	<td>

[link](/file)

</table>
