<input type= "button " value= "粤A粤A粤A " onclick= "ccccc() ">


<script type= "text/javascript ">

function ccccc(){
document.getElementById( "table1 ").childNodes[0].childNodes[0].height=document.getElementById( "table2 ").childNodes[0].childNodes[0].height
}
</script>

<script language= "javascript ">
//document.getElementById( "main ").style.height=document.getElementById( "right ").scrollHeight+ "px "
if(document.getElementById( "right ").scrollHeight < 375){
document.getElementById( "left ").style.height=375+ "px ";
}
else{
document.getElementById( "left ").style.height=document.getElementById( "right ").scrollHeight+ "px ";
}
</script>

老大,你给第一个表格中第二列的行加加上ID属性或嵌套个div,如＜div id= "a "> </div>
第二个表格中的第三行行高＜div id= "b "＞＜／div＞
if(document.getElementById( "a ").scrollHeight < document.getElementById( "b ").scrollHeight){
document.getElementById( "a ").style.height=document.getElementById( "b ").scrollHeight
}
else{
document.getElementById( "b ").style.height=document.getElementById( "a ").scrollHeight+ "px ";
}
