这是我为重现表格而创建的代码笔：
https://codepen.io/NazariyV/pen/OoVdWq
由于某种原因，水平和垂直滚动条的大小不同，我无法完全理解为什么。我也尝试过这种方法，但是根本没有采用（即使我在源代码中看到它使用了正确的.css文件）：
.style-2::-webkit-scrollbar:horizontal
{
width: 12px!important;
}
Codepen HTML：
<div class="results-container">
<div class="header">
<p class="header-description">Filtered Results</p>
<span class="additional-description"></span>
<hr class="underline style-two"/>
</div>
<div id="table-scroll" class="table-scroll style-2">

我知道了，对于水平滚动条，您必须设置高度。
将此CSS添加到您的：
onBlur(e) {
var currentTarget = e.currentTarget;
setTimeout(function() {
if (!currentTarget.contains(document.activeElement)) {
this.setState({
isNavOpen: !this.state.isNavOpen
});
}
}.bind(this), 0);
}
简单的例子：
.style-2::-webkit-scrollbar {
width: 12px;
height: 12px;
background-color: #F5F5F5;
}
.outer {
margin: 50px auto;
padding: 5px;
width: 300px;
height: 300px;
border: 1px solid red;
overflow: scroll;
}
.inner {
width: 600px;
height: 600px;
background: aqua;
}
.outer::-webkit-scrollbar-track {
-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
-moz-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
-ms-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
-o-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
border-radius: 10px;
background-color: #F5F5F5;
}
.outer::-webkit-scrollbar {
width: 12px;
height: 12px;
background-color: #F5F5F5;
}
.outer::-webkit-scrollbar-thumb {
border-radius: 10px;
-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,.3);
-moz-box-shadow: inset 0 0 6px rgba(0,0,0,.3);
-ms-box-shadow: inset 0 0 6px rgba(0,0,0,.3);
-o-box-shadow: inset 0 0 6px rgba(0,0,0,.3);
