如何删除表中的行和列之间的不需要的空间？
如何删除表格中行和列之间的额外空间。
我试着改变表格和tr和td上的边距，填充和各种边界属性。
我希望所有的照片都彼此相邻，看起来像一个大的图像。
我应该如何解决这个问题？
CSS
table {
border-collapse: collapse;
}

它会有效地重置CSS，摆脱填充和边距。
添加到vectran的答案：您还必须在表元素上设置cellspacing属性以实现跨浏览器兼容性。
<table cellspacing="0">
编辑（为了完整起见，我扩大了这5年后:)：
Internet Explorer 6和Internet Explorer 7要求您直接将单元格间距设置为表格属性，否则间距不会消失。
Internet Explorer 8及更高版本以及流行浏览器的所有其他版本 - Chrome，Firefox，Opera 4+ - 支持CSS属性border-spacing。
因此，为了使跨浏览器表格单元格间隔重置（支持IE6作为恐龙浏览器），您可以按照以下代码示例进行操作：
table{
border: 1px solid black;
}
table td {
border: 1px solid black; /* Style just to show the table cell boundaries */
}
table.no-spacing {
border-spacing:0; /* Removes the cell spacing via CSS */
border-collapse: collapse; /* Optional - if you don't want to have double border where cells touch */
}<p>Default table:</p>
<table>
<tr>
<td>First cell</td>
<td>Second cell</td>
</tr>
</table>
<p>Removed spacing:</p>
<table class="no-spacing" cellspacing="0"> <!-- cellspacing 0 to support IE6 and IE7 -->
<tr>
<td>First cell</td>
<td>Second cell</td>
</tr>
</table>这对我有效：
#table {
border-collapse: collapse;
border-spacing: 0;
}
