当滚动条未显示时更改 tbody 的宽度

Question

我有带有滚动条的表格，当我过滤表格时，滚动条未显示，这对我有好处，但问题是宽度正在变化，并且表格宽度变大。 它看起来像这样：

1. 带滚动条：

2. 没有滚动条，过滤后：

这是我的CSS代码：

.table {
  table-layout: fixed;
  width: 100% !important;
}


tbody {
 display: block;
 height: 326px;
 overflow: auto;
 width: 1205px;
}

thead, tbody tfoot, tr {
    display: table;
    width: 100%;
    table-layout: fixed; /* even columns width , fix width of table too*/
}

thead {
   table-layout: fixed;
}

.table tr th:nth-child(1), .table tr td:nth-child(1) {
  width: 30px !important;
}

.table tr th:nth-child(2), .table tr td:nth-child(2) {
  width: 90px !important;
 }

.table tr th:nth-child(3), .table tr td:nth-child(3) {
   width: 100px !important;
 }

 .table tr th:nth-child(4), .table tr td:nth-child(4) {
   width: 90px !important;
 }

 .table tr th:nth-child(5), .table tr td:nth-child(5) {
     width: 90px !important;
 }

 .table tr th:nth-child(6), .table tr td:nth-child(6) {
     width: 90px !important;
 }

 .table tr th:nth-child(7), .table tr td:nth-child(7) {
     width: 85px !important;
 }

 .table tr th:nth-child(8), .table tr td:nth-child(8) {
     width: 90px !important;
 }

 .table tr th:nth-child(9), .table tr td:nth-child(9) {
     width: 110px !important;
 }

.table tr th:nth-child(10), .table tr td:nth-child(10) {
    width: 95px !important;
}

如何解决我的问题？

如果您想确保元素在出现滚动条时不会移动，请在应用了溢出属性的元素上使用 scrollbar-gutter:stable 。见下文。

MDN 上的滚动条装订线 p>

.table {
  table-layout: fixed;
  width: 100% !important;  
}

tbody {
 display: block;
 height: 100px;
 overflow: auto;
 width: 1205px;
  
 /* added this */
 scrollbar-gutter: stable;
}

thead, tbody tfoot, tr {
    display: table;
    width: 100%;
    table-layout: fixed; /* even columns width , fix width of table too*/
}

thead {
   table-layout: fixed;
}

.table tr th:nth-child(1), .table tr td:nth-child(1) {
  width: 30px !important;
}

.table tr th:nth-child(2), .table tr td:nth-child(2) {
  width: 90px !important;
 }

.table tr th:nth-child(3), .table tr td:nth-child(3) {
   width: 100px !important;
 }

 .table tr th:nth-child(4), .table tr td:nth-child(4) {
   width: 90px !important;
 }

 .table tr th:nth-child(5), .table tr td:nth-child(5) {
     width: 90px !important;
 }

 .table tr th:nth-child(6), .table tr td:nth-child(6) {
     width: 90px !important;
 }

 .table tr th:nth-child(7), .table tr td:nth-child(7) {
     width: 85px !important;
 }

 .table tr th:nth-child(8), .table tr td:nth-child(8) {
     width: 90px !important;
 }

 .table tr th:nth-child(9), .table tr td:nth-child(9) {
     width: 110px !important;
 }

.table tr th:nth-child(10), .table tr td:nth-child(10) {
    width: 95px !important;
}
