在我的 Angular 6 应用程序中使用mat-table
时,我无法为水平滚动设置背景颜色mat-header-row
和正确设置背景颜色。mat-row
CSS 属性仅适用于屏幕的可见部分,一旦向右滚动,就不会分配颜色。
我的表中有大约 30 列,所以肯定需要水平滚动。
我的CSS如下:
.mat-toolbar {
font-size: 17px;
font-family: inherit;
background-color: indigo;
max-height: 12vh;
}
.mat-elevation-z8 {
padding: 0px;
}
.mat-table {
overflow: auto;
max-height: 68vh;
min-width: 100%;
}
.mat-header-row {
position: sticky;
top: -.5px;
z-index: 100;
background-color: gainsboro;
font-size: 12px;
min-height: 8vh;
color: #f5f5f5;
padding-top: 3px;
}
.mat-row:nth-child(even) {
background-color: floralwhite;
}
.mat-row:nth-child(odd) {
background-color: gainsboro;
}
.mat-row {
min-height: 8vh;
}
.no-results {
display: flex;
justify-content: center;
padding: 12px;
font-size: 12px;
font-style: italic;
font-family: inherit;
}
.mat-cell {
font-family: inherit;
font-size: 12px;
}
.mat-header-cell {
font-size: 12px;
font-weight: bolder;
}
.mat-cell:nth-child(1),
.mat-header-cell:nth-child(1) {
flex: 0 0 6%;
}
.mat-cell:nth-child(2),
.mat-header-cell:nth-child(2) {
flex: 0 0 9%;
}
.mat-cell:nth-child(3),
.mat-header-cell:nth-child(3) {
flex: 0 0 14%;
}
.mat-cell:nth-child(4),
.mat-header-cell:nth-child(4) {
flex: 0 0 10%;
}
.mat-cell:nth-child(5),
.mat-header-cell:nth-child(5) {
flex: 0 0 10%;
}
.mat-cell:nth-child(6),
.mat-header-cell:nth-child(6) {
flex: 0 0 8%;
}
.mat-cell:nth-child(7),
.mat-header-cell:nth-child(7) {
flex: 0 0 9%;
}
.mat-cell:nth-child(8),
.mat-header-cell:nth-child(8) {
flex: 0 0 8%;
}
.mat-cell:nth-child(9),
.mat-header-cell:nth-child(9) {
flex: 0 0 8%;
}
.mat-cell:nth-child(10),
.mat-header-cell:nth-child(10) {
flex: 0 0 9%;
}
.mat-cell:nth-child(11),
.mat-header-cell:nth-child(11) {
flex: 0 0 8%;
}
.mat-cell:nth-child(12),
.mat-header-cell:nth-child(12) {
flex: 0 0 11%;
}
.mat-cell:nth-child(13),
.mat-header-cell:nth-child(13) {
flex: 0 0 7%;
}
.mat-cell:nth-child(14),
.mat-header-cell:nth-child(14) {
flex: 0 0 11%;
}
.mat-cell:nth-child(15),
.mat-header-cell:nth-child(15) {
flex: 0 0 7%;
}
.mat-cell:nth-child(16),
.mat-header-cell:nth-child(16) {
flex: 0 0 8%;
}
.mat-column-name {
border-right: 1px solid grey;
align-self: stretch;
text-align: center;
}
.mat-column-position {
border-right: 1px solid grey;
align-self: stretch;
text-align: center;
}
.mat-column-weight {
border-right: 1px solid grey;
align-self: stretch;
text-align: center;
}
.mat-column-symbol {
text-align: center;
align-self: stretch;
}
.mat-column-weight {
align-self: stretch;
}
尝试将溢出属性分别设置为 mat-header-row 和 mat-row;它解决了背景颜色,但标题行和数据行可以单独滚动而不同步。
