* remaining 5 columns).</td>
* </tr>
* <tr>
* <td>LCB</td>
* <td>3 components, a label in the 1st column, a component spread across
* the next 4, and a button in the last column.</td>
* </tr>
* <tr>
* <td>LCLC</td>
* <td>4 components, a label in column 1, a component in 2-3, a label in
* 4 and a component in 5-6.</td>
