如何使工具提示完全可见，隐藏回表头。我尝试增加z-index值和位置，但它没有工作。我已经附加了我的css代码。
这是我的css文件：
/* Base styles for the element that has a tooltip */
[data-tooltip],
.tooltip {
position: relative;
cursor: pointer;
}
/* Base styles for the entire tooltip */
[data-tooltip]:before,
[data-tooltip]:after,
.tooltip:before,
.tooltip:after {
position: absolute;
visibility: hidden;
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0);
opacity: 0;
-webkit-transition:
opacity 0.2s ease-in-out,
visibility 0.2s ease-in-out,
-webkit-transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
-moz-transition:
opacity 0.2s ease-in-out,
visibility 0.2s ease-in-out,
-moz-transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
transition:
opacity 0.2s ease-in-out,
visibility 0.2s ease-in-out,
transform 0.2s cubic-bezier(0.71, 1.7, 0.77, 1.24);
-webkit-transform: translate3d(0, 0, 0);
-moz-transform: translate3d(0, 0, 0);
transform: translate3d(0, 0, 0);
pointer-events: none;
}
/* Show the entire tooltip on hover and focus */
[data-tooltip]:hover:before,
[data-tooltip]:hover:after,
[data-tooltip]:focus:before,

您可以在此处向工具提示添加position: absolute，并将position: relative应用于thead。
将顶部显示工具提示。
