我有一个带有固定标题和固定第一列的表格。
我还想将列标题旋转 45 度。
固定标题需要设置背景颜色。但是，这会导致 45 度旋转标题出现问题，因为下一栏的背景与前一栏的文本重叠。以下是问题的示例：
.fixed_table {
white-space: nowrap;
margin: 0;
border: none;
border-collapse: separate;
border-spacing: 0;
table-layout: fixed;
}
.fixed_table td,
.fixed_table th {
padding: 5px;
}
.fixed_table thead th {
padding: 5px;
position: sticky;
top: 0;
z-index: 1;
width: 25vw;
background: #F8F9FA;
}
.fixed_table td {
background: #F8F9FA;
padding: 5px;
text-align: center;
border: 1px solid #ccc;
}
.fixed_table tbody th {
text-align: left;
position: relative;
}
.fixed_table thead th:first-child {
position: sticky;
left: 0;
z-index: 2;
}
.fixed_table tbody th {
position: sticky;
left: 0;
background: #F8F9FA;
z-index: 1;
}
th.rotate {
/* Something you can count on */
height: 140px;
white-space: nowrap;
}
th.rotate > div {
transform:
/* Magic Numbers */
translate(25px, 51px)
/* 45 is really 360 - 45 */
rotate(315deg);
width: 30px;
}
th.rotate > div > span {
border-bottom: 1px solid #ccc;
padding: 5px 10px;
}
<div style="height: 100%; width: 100%; overflow-y: scroll; background-color: #F8F9FA; height: 400px;">
<table class="fixed_table">

如果我不设置背景颜色，行会滚动列标题：
.fixed_table {
white-space: nowrap;
margin: 0;
border: none;
border-collapse: separate;
border-spacing: 0;
table-layout: fixed;

.fixed_table th {

.fixed_table thead th {
padding: 5px;

background: transparent;
}
.fixed_table td {
background: #F8F9FA;
padding: 5px;
text-align: center;
border: 1px solid #ccc;
}
.fixed_table tbody th {
text-align: left;
position: relative;
}
.fixed_table thead th:first-child {
position: sticky;
left: 0;
z-index: 2;
}
.fixed_table tbody th {
position: sticky;

}
th.rotate {

}
th.rotate > div {

translate(25px, 51px)
/* 45 is really 360 - 45 */
rotate(315deg);

}
th.rotate > div > span {

是否有人有解决方案来 (a) 保持标题固定并且不显示在其后面向上滚动的行数据，以及 (b) 让所有 45 度旋转的标题仍然正确显示？
提前致谢！
尝试以下代码：
.fixed_table thead th { padding: 5px; position: sticky; top: 0; z-index: 1; background-color: white; width: 25vw; /* background: transparent; */ }我希望这会有所帮助。
