如何将滚动条添加到HTML5表？

Question

我有一个HTML5表,我想添加一个滚动条.我希望表格显示十行,然后用户可以向下滚动以查看其他歌曲.如何添加滚动条？

这是我在HTML5中的表的代码:

<table id="my_table" table border="5">
  <tr>
    <th>URL</th>
  </tr>
  <tr>
    <td>http://www.youtube.com/embed/evuSpI2Genw</td>
  </tr>
  <tr>
    <td>http://www.youtube.com/embed/evuSpI2Genw</td>
  </tr>
</table>

这是我的CSS代码:

#my_table {
    border-radius: 20px;
    background-color: transparent;
    color: black;
    width: 500px;
    text-align: center;
}

Answer 1

如果您已经前往表格列并且不想滚动这些标题,那么此解决方案可以帮助您:

此解决方案需要thead并tbody标记table元素内部.

table.tableSection {
    display: table;
    width: 100%;
}
table.tableSection thead, table.tableSection tbody {
    float: left;
    width: 100%;
}
table.tableSection tbody {
    overflow: auto;
    height: 150px;
}
table.tableSection tr {
    width: 100%;
    display: table;
    text-align: left;
}
table.tableSection th, table.tableSection td {
    width: 33%;
}

注意:如果您确定始终存在垂直滚动条,则可以使用css3 calc属性使thead单元格与tbody单元格对齐.

table.tableSection thead {
    padding-right:18px;   /* 18px is approx. value of width of scroll bar */
    width: calc(100% - 18px);
}

你可以通过使用javascript检测滚动条的存在并应用上述样式来做同样的事情.

Answer 2

而不是假设固定宽度列.

CSS

table.tableSection {
  display: table;
  width: 100%;
}

table.tableSection thead,
table.tableSection tbody {
  width: 100%;
}

table.tableSection thead {
  overflow-y: scroll;
  display: table;
  table-layout: fixed;
  width: calc(100% - 16px); /* assuming scrollbar width as 16px */
}

table.tableSection tbody {
  overflow: auto;
  height: 150px;
  display: block;
}

table.tableSection tr {
  width: 100%;
  text-align: left;
  display: table;
  table-layout: fixed;
}

这是我在很多场合使用的技术.它最初是基于这个小提琴的一些修改.它也是流体,并且可以通过添加宽度样式来固定列宽<th>.

/* this is for the main container of the table, also sets the height of the fixed header row */
.headercontainer {
  position: relative;
  border: 1px solid #222;
  padding-top: 37px;
  background: #000;
}
/* this is for the data area that is scrollable */
.tablecontainer {
  overflow-y: auto;
  height: 200px;
  background: #fff;
}

/* remove default cell borders and ensures table width 100% of its container*/
.tablecontainer table {
  border-spacing: 0;
  width:100%;
}

/* add a thin border to the left of cells, but not the first */
.tablecontainer td + td {
  border-left:1px solid #eee; 
}

/* cell padding and bottom border */
.tablecontainer td, th {
  border-bottom:1px solid #eee;
  padding: 10px;
}

/* make the default header height 0 and make text invisible */
.tablecontainer th {
    height: 0px;
    padding-top: 0;
    padding-bottom: 0;
    line-height: 0;
    visibility: hidden;
    white-space: nowrap;
}

/* reposition the divs in the header cells and place in the blank area of the headercontainer */
.tablecontainer th div{
  visibility: visible;
  position: absolute;
  background: #000;
  color: #fff;
  padding: 9px 10px;
  top: 0;
  margin-left: -10px;
  line-height: normal;
   border-left: 1px solid #222;
}
/* prevent the left border from above appearing in first div header */
th:first-child div{
  border: none;
}

/* alternate colors for rows */
.tablecontainer tbody  tr:nth-child(even){
     background-color: #ddd;
}

<div class="headercontainer">
  <div class="tablecontainer">

Answer 4

问题问题已经过去了一年左右,但我对答案并不满意.我摆弄了一段时间,这是一个代码:

• 适用于IE8 +和所有其他浏览器;
• 很容易理解;
• 完美地排列细胞边界(固定宽度的细胞);
• 在身体滚动的同时固定头部;
• 自动适应触摸屏.
