修复 Bootstrap 表的第一列

Question

我按照@koala_dev 在 这篇文章 中的代码尝试锁定第一列 s 我的表水平滚动。不幸的是，代码对我的表没有影响。我想知道是否有人可以给我一些关于我做错了什么的指示，因为我是编程新手。

这是我的桌子：http: //jsfiddle.net/mademoiselletse/bypbqboe/59/

这是我在 JS 中插入的代码（第 121-133 行）：

 $(function() {
    var $tableClass = $('.table');
    // Make a clone of our table
    var $fixedColumn = $tableClass.clone().insertBefore($tableClass).addClass('fixed-column');

    // Remove everything except for first column
    $fixedColumn.find('th:not(:first-child),td:not(:first-child)').remove();

    // Match the height of the rows to that of the original table's
    $fixedColumn.find('tr').each(function(i, elem) {
      $(this).height($tableClass.find('tr:eq(' + i + ')').height());
    });
});

这是我插入的 CSS 属性（第 36-47 行）：

 .table-responsive > .fixed-column {
   position: absolute;
   display: inline-block;
   width: auto;
   border-right: 1px solid #ddd;
}

@media(min-width:768px) {
    .table-responsive>.fixed-column {
        display: none;
    }
}

The only thing I deviated from the demo code was that I defined $('.table') as $tableClass instead of $table since I have previously defined var $table as $('#table') 。非常感谢您的帮助！

Answer 1

好的..删除你所有的 js 代码，你可以用下面的一些CSS技巧来做到这一点：

演示

CSS

 .table > thead:first-child > tr:first-child > th:first-child {
    position: absolute;
    display: inline-block;
    background-color: red;
    height: 100%;
}

.table > tbody > tr > td:first-child {
    position: absolute;
    display: inline-block;
    background-color: red;
    height: 100%;
}

.table > thead:first-child > tr:first-child > th:nth-child(2) {
    padding-left: 40px;
}

.table > tbody > tr > td:nth-child(2) {
    padding-left: 50px !important;
}

只需将 position:sticky 添加到 th & td first-child 。

 th:first-child, td:first-child
{
  position:sticky;
  left:0px;
  background-color:grey;
}
