Row or Column ?

Question

I feel this question needs to specify what cells are been expanded into if its either a column or row

Answer 1

It's column.
With a number of cells you add to your table will lead you to create a new column each time.
eg.
<table>
<tr>
<td>c1r1</td>
<td>c2r1</td>
<td>c3r1</td>
</tr>
<tr>
<td>c1r2</td>
<td>c2r2</td>
<td>c3r2</td>
</tr>
</table>

Above code has 2 rows and 3 columns defined by the cells (<td>).
