如何为 TBODY 应用垂直滚动条

我的表中有 4 列和 5 行数据。我必须为 TBODY 应用垂直滚动条，TH 标题内容不应滚动。

我对场景进行了编码，并且在我将滚动类应用于 TBODY 之前它工作正常。一旦我将滚动样式类应用于 TBODY，它就会破坏之前的对齐方式。任何人都可以帮助解决这个问题..谢谢

 <table class="banker-list">
            <colgroup><col width="40%"><col width="23%"><col width="24%"><col width="13%"></colgroup>

TABLE {
    border-collapse: collapse;
    width: 100%;
}
P, TABLE {
    font-family: Verdana;
    text-align: left;
}
.dataRow {
    margin-bottom: 5px;
    margin-top: 5px;
}
.fieldLabel {
    color: #000000;
    font-size: 85%;
    font-weight: bold;
}
.bankerScroll {
    display:block;overflow:auto;height:100px;white-space:nowrap;
}

这是一个工作示例：

您必须将 display:block 添加到 thead > tr 和 tbody
