[求助]表格的文字不会在单元格中居中显示

<table style="border: 1px solid black;BORDER-COLLAPSE:COLLAPSE" border="1" align="center" width="90%" class="tableClass61" cellSpacing="0" cellPadding="0" bordercolor="#000000" bordercolorLight="#000000" bordercolorDark="#ffffff">
<%
response.write"<tr>"
response.write"<td width=50 align=middle height=30>需求主旨</td>"
response.write"<td width=50 align=middle>需求单位</td>"
response.write"<td width=60 align=middle>需求提出人</td>"
response.write"<td width=50 align=middle>需求编号</td>"
response.write"<td width=50 align=middle>资讯主办</td>"
response.write"<td width=50 align=middle>提出日期</td>"
response.write"<td width=80 align=middle>希望上线日期</td></tr>"
</table>
奇怪了,为什么我用了align=middle,那些文字在单元格中还是靠左显示
