在table中设置border-radius发现不起作用，网上查找了一番，原因是border-collapse:collapse和border-radius不兼容。
css:
border-collapse: separate;
border-spacing: 0;设计图效果
代码实现效果：
<!DOCTYPE html>
<html><head lang="en"> <meta charset="UTF-8"> <title></title> <style> #table_wrap > table { font-size: 16px; text-align: center; margin: 0 auto; border-collapse: separate; border-spacing: 0; border: 2px #000; }table thead tr,table tbody tr {
height: 50px; line-height: 50px; /*background-color: pink;*/ } table tr th:first-child,table tr td:first-child {/*设置table左边边框*/ border-left: 2px solid #eaeaea; } table tr th:last-child,table tr td:last-child {/*设置table右边边框*/ border-right: 2px solid #eaeaea; } table tr td:first-child, table tr td:nth-child(2), table tr td:nth-child(3), table tr td:last-child{/*设置table表格每列底部边框*/ border-bottom: 2px solid #eaeaea; } /*table tr:last-child td:first-child, table tr:last-child td:nth-child(2), table tr:last-child td:nth-child(3), table tr:last-child td:last-child{/!*设置table表格最后一列底部边框*!/ border-bottom: 2px solid #000; }*/ table tr th { background: #eaeaea; } table tr:first-child th:first-child { border-top-left-radius: 12px; }table tr:first-child th:last-child {
border-top-right-radius: 12px; } table tr:last-child td:first-child { border-bottom-left-radius: 12px; }table tr:last-child td:last-child {
border-bottom-right-radius: 12px; }</style>
</head><body><div id="table_wrap"> <table class="table" width="800" cellspacing="0" cellpadding="0"> <thead class="table_head"> <tr> <th>头部1</th> <th>头部2</th> <th>头部3</th> <th>头部4</th> </tr> </thead> <tbody> <tr> <td>1内容1</td> <td>1内容2</td> <td>1内容3</td> <td>1内容4</td> </tr> <tr> <td>2内容1</td> <td>2内容2</td> <td>2内容3</td> <td>2内容4</td> </tr> <tr> <td>3内容1</td> <td>3内容2</td> <td>3内容3</td> <td>3内容4</td> </tr> </tbody> </table></div></body></html>
