我有一个 GridView ，其中某些框以绿色突出显示。这些盒子应该填满整个盒子，但我似乎无法在边缘周围丢弃这个 1px 的边框。我正在使用 IE7，但 FF 也可以。

更新
更改了 Serial# 模板的元素样式并解决了该问题。我不知道为什么，但多亏了你的提示，我能够将问题减少到足以尝试的程度:
<ItemStyle Font-Size="Smaller" CssClass="NoMargin NoPadding" />
最佳答案
尝试设置 border-collapse: collapse;在 cssTable CSS 类上。
好的，我能够让它工作。我从第一个模板项中删除了 css 类并创建了以下 css。
table.cssTable
{
border-collapse: collapse;
}
table.cssTable tr td
{
background: Yellow;
font-size:Smaller;
margin: 0;
padding: 0;
}
顺便说一下，您应该能够使用此 CSS 摆脱带有字体大小的 ItemStyle。
