将工具提示添加到具有固定 header 和左列的 table

Question

我正在尝试将工具提示添加到具有固定 headers 和左列的可滚动 table。当我添加工具提示时，当滚动 table 时，单元格不再隐藏在固定的 headers 和列后面。

<HTML>
<HEAD>
<STYLE>
.gradebooktable {
  overflow: auto;
  height: 100px;
  width: 400px
}

table {
  table-layout: fixed;
  border-width: 0;
  border-spacing: 0;
}

td {
  padding: 3px;
  white-space: nowrap;
  border-right: 1px solid #ccc;
}

th {
  background: #999;
}

th.pinned {
  position: relative; 
  z-index: 20;        
  background: #ccc;
}

td.pinned {
  background: #eee;
}

.tooltip{
  position:relative;
}

.tooltipcomment{
  display:none;
  position:absolute; 
  z-index:10;
  border:1px;
  background-color:white;
  border-style:solid;
  border-width:1px;
  border-color:blue;
  padding:3px;
  color:red; 
  top:20px; 
  left:20px;
}

.tooltip:hover span.tooltipcomment{
  display:block;
}

</style>

这里有一个 fiddle 显示问题：

https://jsfiddle.net/6jh60sgs/9/

我需要做什么才能使带有工具提示的单元格滚动到固定 headers 和列的后面？

Answer 1

试试这个，我之前已经测试过你的代码并且可以工作

只需更改工具提示 class

像这样

.tooltip{
 position:relative;
 display: none;
 }

Answer 2

我修好了：https://jsfiddle.net/k42myms3/1/

.gradebooktable {
  overflow: auto;
  height: 200px;
  width: 400px
}

table {
  table-layout: fixed;
  border-width: 0;
  border-spacing: 0;
}

td {
  position:relative;
  padding: 3px;
  white-space: nowrap;
  border-right: 1px solid #ccc;
}

th {
  position:relative;
  z-index:20; 
  background: #999;
}

th.pinned {
  position: relative; 
  z-index: 40;     
  background: #ccc;
}

td.pinned {
  position: relative;
  z-index: 30; 
  background: #eee; 
}

.tooltip{
  position:relative;
}

.tooltiptext{
  display:none;
  position:absolute; 
  z-index:10;
  border:1px;
  background-color:#eee;
  border-style:solid;
  border-width:1px;
  border-color:blue;
  border-radius: 6px;
  padding:3px;
  color:blue; 
  top:20px; 
  left:20px;
}

.tooltip:hover span.tooltiptext{
  display:block;
}
