Right align and left align text in same HTML table cell

Answer 1

td style is not necessary but will make it easier to see this example in browser

<table>
 <tr>
  <td style="border: 1px solid black; width: 200px;">
  <div style="width: 50%; float: left; text-align: left;">left</div>
  <div style="width: 50%; float: left; text-align: right;">right</div>
  </td>
 </tr>
</table>

Answer 2

It is possible but how depends on what you are trying to accomplish. If it's this:

| Left-aligned       Right-aligned | in one cell then you can use floating divs inside the td tag:

<td>
<div style='float: left; text-align: left'>Left-aligned</div>
<div style='float: right; text-align: right'>Right-aligned</div>
</td>

If it's | Left-aligned
                                           Right Aligned |

Then Balon's solution is correct.

If it's: | Left-aligned    |   Right-Aligned |

Then it's:

<td align="left">Left-aligned</td>
<td align="right">Right-Aligned</td>
