Html 如何使我的4篇文章（2栏）具有相同的高度？

请看一看:

HTML:

<table class="art-article" border="0" cellspacing="0" cellpadding="0" style="width:100%;">
<col width="50%" />
<col width="50%" />
    <tbody>
        <tr>
            <td><table class="metaart"  width="100%" border="0">
                    <tbody>
                        <tr>

标题中阴影效果和渐变的css代码位于btm的css部分

第二个问题。。我应该把填充的代码放在哪里，以增加文本和文本框之间的空间

将表放在一个表中，或重新组织成一个表，其中表1是第一列等
