如何在带有溢出的容器中显示纯CSS工具提示：隐藏

Question

下面的css在悬停时显示来自数据属性的工具提示，但是当容器Select Unnest(xpath('//@ActionID',XMLCONTENT)) as ID, Unnest(xpath('//@MessageID',XMLCONTENT)) as MessageID, Unnest(xpath('//@Operator',XMLCONTENT)) as Operator 具有td时要显示整个数据属性时，不适用于该用例。

删除overflow: hidden会启用工具提示，但会破坏省略号。

overflow: hidden

您可以将文本放在<p>标记中，然后在其中添加overflow:hidden吗？

html {
  box-sizing: border-box;
}

*,
*:before,
*:after {
  box-sizing: inherit;
}

body {
  margin: 64px auto;
  text-align: center;
  font-size: 100%;
  max-width: 640px;
  width: 94%;
}

a:hover {
  text-decoration: none;
}

header,
.demo,
.demo p {
  margin: 4em 0;
  text-align: center;
}

[data-tooltip] {
  position: relative;
  z-index: 2;
  cursor: pointer;
}

[data-tooltip]:before,
[data-tooltip]:after {
  visibility: hidden;
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
  filter: progid: DXImageTransform.Microsoft.Alpha(Opacity=0);
  opacity: 0;
  pointer-events: none;
}

[data-tooltip]:before {
  position: absolute;
  bottom: 150%;
  left: 50%;
  margin-bottom: 5px;
  margin-left: -80px;
  padding: 7px;
  /*width: 160px;*/
  -webkit-border-radius: 3px;
  -moz-border-radius: 3px;
  border-radius: 3px;
  background-color: #000;
  background-color: hsla(0, 0%, 20%, 0.9);
  color: #fff;
  content: attr(data-tooltip);
  text-align: center;
  font-size: 14px;
  line-height: 1.2;
}

[data-tooltip]:after {
  position: absolute;
  bottom: 150%;
  left: 50%;
  margin-left: -5px;
  width: 0;
  border-top: 5px solid #000;
  border-top: 5px solid hsla(0, 0%, 20%, 0.9);
  border-right: 5px solid transparent;
  border-left: 5px solid transparent;
  content: " ";
  font-size: 0;
  line-height: 0;
}

[data-tooltip]:hover:before,
[data-tooltip]:hover:after {
  visibility: visible;
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
  filter: progid: DXImageTransform.Microsoft.Alpha(Opacity=100);
  opacity: 1;
}

.name {}

p {
  overflow: hidden;
  max-width: 200px;
  text-overflow: ellipsis;
  white-space: nowrap;
  margin: 0;
}

<table>
  <tr>
    <td>One</td>
    <td class="name" data-tooltip="dsfsdfsdfsdfsdfsdfsdfsdfsdfsdfsdfsd">
      <p>dsfsdfsdfsdfsdfsdfsdfsdfsdfsdfsdfsd</p>
    </td>
    <td>Three</td>
  </tr>
</table>

我也建议不要限制工具提示（[data-tooltip]:before）的宽度，因为它会切断您的文本。我修改了上面的示例以注释掉宽度。
