Tip #110: text->html table converter.

Below are two functions and a mapping which will convert lines of plain text into
HTML table code.
For example, you have several lines like:
-----------------------------------------------
1
2
3

4
5
6
---------------------------------------------------
by visualizing all the 7 lines and press <F5>, you can change the text into
<table><tr>
   <td>1</td>
   <td>2</td>
   <td>3</td>
</tr><tr>
   <td>4</td>
   <td>5</td>
   <td>6</td>
</tr></table>
which will eventually render into a table.
So the rule is:
Every line is a table item, every empty line means starting of a new table row.
