为什么表格标题不使用宽度设置？

时间：2018-08-12 20:50:50

标签： html css

这支笔的目的是使表的主体滚动而不滚动标题。
该部分有效，但是我无法使标头散布在HTML正文中以匹配数据行。我究竟做错了什么？

在此先感谢您的帮助。

简单语法错误。您在第5行的末尾有一个;。

以display: flex样式使用justify-content: space-around和thead tr。

body { 
  margin: 0; 
  padding: 0; 
  height: 100vh; 
}
div { 
  background-color: green; 
  width: 100%; 
  height: 100%;
}
table { 
  width: 100%;
  background-color: red;
  height: 100%;
  display: flex; 
  flex-direction: column;  
}
thead { 
  background-color: purple;
  width: 100%;
  display: block;
}
thead tr { 
  background-color: orange; 
  width: 100%; 
  overflow: hidden;
  display: flex;
  justify-content: space-around; 
}
thead tr td { 
  min-width: 30%;
  width: 30%;
  display: inline-block; 
}
tbody { 
  flex: 1;
  background-color: blue;

答案 2 :(得分：0)

我已经设法获得一个简单的滚动表和固定的标题，并使用显示阻止项来控制列宽。

在此处http://jsfiddle.net/joshmoto/xjq41yng/4/中查看jsfiddle 

table {
  width: 100%; /* your table width */
  background: blue;
  border: 0;
  border-spacing: 0;
}

thead,
tbody,
tr,
td,
th {
  display: block;
  padding: 0;
}

tr:after {
  content: ' ';
  display: block;
  visibility: hidden;
  clear: both;
}

thead th {
  height: 30px;
  background: orange;
}

tbody td {
  background: aqua;
}

tbody {
  height: 120px; /* fixed tbody height to show scroll example */
  overflow-y: auto;
}

tbody td,
thead th {
  width: 30%; /* your column width */
  float: left;
}
<table>
  <thead>
    <tr>
      <th>Header A</th>
      <th>Header B</th>
      <th>Header C</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>A</td>
      <td>B</td>
      <td>C</td>
    </tr>
    <tr>
      <td>A</td>
      <td>B</td>
      <td>C</td>
    </tr>
    <tr>
      <td>A</td>
      <td>B</td>
      <td>C</td>
    </tr>
    <tr>

    <tr>

      <td>C</td>
    </tr>
    <tr>
      <td>A</td>
