- 表格的基础构造
- 边距和边线应用
- 隐藏和删除应用
- 简单表格
table {
auto;
border-collapse:collapse;（把单元格空隙合并起来）
margin-left:20px;
border:1px solid black;
}
td,th {
50px;
border:1px solid black;
padding:5px;
background:gold;
text-align:center;
vertical-align:middle;
text-indent:5px;
}

</table>
<table>
<tr><th rowspan="2">1</th><th colspan="2">2</th></tr>
<tr><td>8</td><td>9</td><td>10</td><td>11</td><td>12</td></tr>

}
td,th {
50px;
padding:5px;
text-align:center;
vertical-align:middle;
background:gold;
text-indent:5px;

<table>
<colgroup>
<col class="hidden delete" />
</colgroup>
<tr><td class="delete">1</td><td>2</td><td>3</td><td>4</td></tr>
<tr>
<td class="hidden">5</td>
<td class="hidden">6</td>
<td>7</td>
<td>8</td>
</tr>
</table>
- 垂直对齐数据
.x {
vertical-align:middle;
}
8.鼠标悬浮时表格颜色替换
table th:hover{
background:green;
}
table td:hover{
background:blue;
}
