<style type="text/css">
<!--
.table_tile{
text-align:left;
height: 20px;
width: 25%;
float: left;
}
.table_tile_{
text-align:right;
background-color:#0000FF;
height: 20px;
background-color:#999966;
width: 25%;
float: left;

复制代码代码如下:
<div class="table_tr">
<div class="table_tile">top0</div>
<div class="table_tile_">top1</div>
<div class="table_tile">top2</div>
<div class="table_tile">top3</div>
</div>
<div class="table_tr">
<div class="table_tile_bottom">bottom0</div>
<div class="table_tile_bottom">bottom1</div>
<div class="table_tile_bottom">bottom2</div>

text-align:left;
height: 20px;
width: 25%;
float: left;
}
</style>
<div class = "float_left">asdasd</div>
<div class = "float_left">asdasd</div>
<div class = "float_left">why</div>
