< table>固定< thead>和可滚动的< tbody> [英] <table> with fixed <thead> and scrollable <tbody>

问题描述

我在网上浏览了这里的问题和文章，但是还没有找到满足我要求的解决方案.因此，在2017年现在，是否有一种优雅的方式来实现<table>:

I've looked through questions here and articles all over the internet, but haven't found yet solution that would satisfy my requirements. So now in 2017, is there an elegant way to have a <table> that would:

1. 用html + css编写(不使用js)
2. 具有固定的标题(不可滚动；不发粘)
3. 具有可滚动的<tbody>(滚动条可能始终可见)
4. 标题和正文将正确处理大小调整，并且不会弄乱<thead>列和<tbody>列的对齐方式
5. 不会为标题使用嵌套表或单独的表

1. be written in html+css (no js)
2. have fixed header (not scrollable; not sticky)
3. have scrollable <tbody> (scrollbar may be always visible)
4. header and body would handle resizing properly and not mess alignment of the <thead> columns and the <tbody> columns
5. would not use nested tables or separate table for header

推荐答案

此解决方案满足所有5个要求:

This solution fulfills all 5 requirements:

table {
  width: 100%;
}

table, td {
  border-collapse: collapse;
  border: 1px solid #000;
}

thead {
  display: table; /* to take the same width as tr */
  width: calc(100% - 17px); /* - 17px because of the scrollbar width */
}

tbody {
  display: block; /* to enable vertical scrolling */
  max-height: 200px; /* e.g. */
  overflow-y: scroll; /* keeps the scrollbar even if it doesn't need it; display purpose */
}

th, td {
  width: 33.33%; /* to enable "word-break: break-all" */
  padding: 5px;
  word-break: break-all; /* 4. */
}

tr {
  display: table; /* display purpose; th's border */
  width: 100%;
  box-sizing: border-box; /* because of the border (Chrome needs this line, but not FF) */
}

td {
  text-align: center;
  border-bottom: none;
  border-left: none;
}

<table> 
  <thead> 
    <tr>
      <th>Table Header 1</th>
      <th>Table Header 2</th>
      <th>Table Header 3</th>
    </tr>
