I dont undestand why the word(colspan) used here....?

Question

<table border="2">
<tr>
<td>Red</td>
<td>Blue</td>
<td>Green</td>
</tr>
<tr>
<td><br /></td>
<td colspan="2"><br /></td>
</tr>
</table>

Answer 1

Col stands for column.

Colspan="2" means that at this spot, a column occupies the space of two columns.
