Easier to type? Sure, but I don't think HTML5 tables are easier to read than markdown tables
<table>
<tr>
<td>first row, first column
<td>first row, second column
<td>first row, third column
<tr>
<td>second row, first column
<td>second row, second column
<td>second row, third column
</table>
Does it get any better in markdown? | first row, first column | first row, second column | first row, third column |
| ------------------------ | ------------------------- | ------------------------ |
| second row, first column | second row, second column | second row, third column |
To me, this is more readable than the HTML version. | first row, first column | first row, second column | first row, third column |
| ------------------------ | ------------------------- | ------------------------ |
| second row, first column | exceptionally long second row, that makes second column look worse | second row, third column |
