Alignment in table cells

I'm having weird issues with table cell right-alignment in the second
row of a table.

Given the following cut-down table

<TABLE WIDTH="100%" BORDER="1">
<TR>
<TD ALIGN="LEFT" WIDTH="20%">left align</TD>
<TD ALIGN="CENTER">
center align</TD>
<TD ALIGN="RIGHT"WIDTH="20%">
right align</TD>
</TR>
<TR>
<TD ALIGN="LEFT" WIDTH="50%">left align</TD>
<TD align="right"WIDTH="50%">right align</TD>
</TR>
</TABLE>


I find that the right-aligned data in the second row is apparently
centre-aligned: adding visible borders indicates that (despite the
explicit width definitions in these cells) the cells in the second row
are being created with the same width as the corresponding cells in the
first row, in other words, there is a blank space to the right of the
row corresponding to the 'missing' third cell.

This code used to display as expected on Netsurf 2.9 - am I abusing HTML
here? Is it no longer legal to have differing numbers of cells, or
cells of differing widths, per row in an HTML table?
