Okay, let's see:
//PHONE
<table>
<tr>
<td>COL 1</td>
<td>COL 2</td>
</tr>
<tr>
<td>COL 1</td>
<td>COL 2</td>
</tr>
</table>
//TABLET E MAIORES
@media only screen and (max-width : 768px) { table>tr>td {...} }
@media only screen and (max-width : 1024px) { table>tr>td {...} }
<table>
<tr>
<td>COL 1</td>
<td>COL 2</td>
<td>COL 3</td>
</tr>
<tr>
<td>COL 1</td>
</tr>
</table>
Is it possible to do this? When you're on the phone a tr with two td, tablets begin to have a tr with 3 td then with 4 and so on ...
