The ALIGN attribute in a TD (table cell definition) tag specifies how the contents of the table cell are to be aligned within the cell boundaries.
In this case, LEFT alignment is being specified -
if the cell is wider than its contents,
perhaps because other cells in the same column have more in them,
then the contents of <em>this</em> cell will be placed leftmost in the cell.
<P>
Other legal alignment values are CENTER and RIGHT.
<P>
Netscape also implements a VALIGN (Vertical ALIGN) attribute,
for which legal values are TOP, BOTTOM, CENTER and BASELINE.
<P>
(The ALIGN and VALIGN attributes may also be supplied in a TR tag,
determining the default horizontal and vertical alignment of the cells in a row.
The TABLE tag may also have an ALIGN attribute, but it has a different meaning
- it specifies that the table is <em>as a whole</em> is to be left or right
justified, and text flowed around it.)
