位置:在<table>元素上粘贴(firefox)

Question

位置的新价值对我来说非常混乱..很多搜索结果都给出了javascript/jQuery(JavaScript框架)解决方案.

在底部的例子中我有一个table与一个thead和tbody.

无论我做什么都达不到欲望的结果.欲望的结果是对桌子的粘性.粘性意味着当不在视野中时,元素是某种position:fixed固定的方式,它会粘在你的屏幕上. 我做了什么尝试:

• display: inline/block/inline-block;
• th元素position:sticky(th元素是tr女巫内部的元素在thead元素内)
• 混合display:inline/block等; (财产价值显示)

我只是找不到如何在firefox中实现这个粘性(支持)

有解决方案??

(position:sticky仍然是一个实验性的API,不应该在生产网站上使用http://developer.mozilla.org/en/docs/Web/CSS/position)

table {
  background-color: rgba(241, 31, 0, 0.3);
  width: 100%;
}
thead {
  background-color: rgba(241, 0, 241, 0.3);
  position: -webkit-sticky;
  position: sticky;
}
th {} tbody td:nth-child(2) {
  height: 200px;
}

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

Answer 1

Firefox 似乎不允许在表子元素上使用"粘性".

一种解决方法是设置table为block,那么thead,tbody,tfoot以display:table;使它们中的一个可以贴.

不幸的是,这打破了表格布局和拆分表到几个表.. :(

你还需要设置coordonates,其中粘性来自 http://codepen.io/gc-nomade/pen/reoExq.不是最好的:(

CSS基础就像:

table {
  display: block;
}

thead {
  position: sticky;
  top: 0px;  /* trigger sticky when reaches coordonates */
}

thead, tbody, tfoot {
  display: table;
  width: 100%;
}

table {
  background-color: rgba(241, 31, 0, 0.3);
  width: 100%;
  margin-top: 1em;
  position: static;
  display: block;
}
thead {
  display: table;
  width: 100%;
  background-color: rgba(241, 0, 241, 0.3);
  position: sticky;
  top: 0px;
  /* trigger sticky when reaches coordonates */
}
tbody {
  display: table;
  width: 100%;
}
th {} tbody td:nth-child(2) {
  height: 200px;
}

Answer 2

另一种方法是使用css3来转换标题单元格.这个方法确实需要javascript并且可以在所有现代浏览器中使用,但是因为它翻译了表格单元格,因此出于某种原因不会包含边框(演示)

此外,此css必须在翻译的单元格上包含背景颜色

thead th,
caption {
  background: #fff;
}

jQuery的

var $win = $(window),
  $table = $('table'),
  $thead = $table.children('thead'),
  $tfoot = $table.children('tfoot'),
  $caption = $table.children('caption'),
  $cells = $thead.children().children().add($caption);

$win.on('scroll', function() {
  var bottom = $table.position().top +
        $table.height() -
        $thead.height() -
        ($tfoot.height() || 0),
    delta = $win.scrollTop() -
        $thead.offset().top +
        $caption.outerHeight(),
    // include border thickness (minus 2)
    vertPos = (delta < 0 || delta > bottom ? 0 : delta - 2);
  $cells.css("transform", "translate(0px," + vertPos + "px)");
});
