我有一个mat-table,我使用以下css将标题和单元格对齐：

.center-align.mat-header-cell {
  display: flex !important;
  justify-content: center !important;
  padding-left: 18px !important;
}
.center-align.mat-footer-cell {
  display: flex !important;
  justify-content: center !important;
}
.center-align.mat-cell {
  display: flex !important;
  justify-content: center !important;
}
.left-align.mat-header-cell {
  padding-right: 18px !important;
}

我最终得到的是：My Table

这是stackblitz中的代码

我想解决的问题是其中一个列标题(“金额9列名”)正在被包装.有足够的空间使其他列稍微窄一些.
有没有办法让单元格自动调整大小,因为这个标题没有被包裹？我已经看到一些其他帖子围绕手动设置其他列的列宽使用类似的东西：

.mat-column-position {
  flex: 0 0 100px;
}

但如果可以,我想避免这样做.我不想在每个页面上遍历每个表格并调整多个列.
谢谢.

更新：
我仍然没有解决这个问题,但如果我将html更新为：

<div class="mat-elevation-z8">
<table mat-table [dataSource]="dataSource"  matSort>
      <ng-container matColumnDef="name">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="left-align"> Name </th>
         <td mat-cell *matCellDef="let element" class="left-align"> {{element.name}} </td>
      </ng-container>
      <ng-container matColumnDef="position">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="center-align"> Position </th>
         <td mat-cell *matCellDef="let element" class="center-align"> {{element.position}} </td>
      </ng-container>
      <ng-container matColumnDef="amount">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="center-align"> Amount</th>
         <td mat-cell *matCellDef="let element" class="center-align"> {{element.amount}} </td>
      </ng-container>
      <ng-container matColumnDef="amount2">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="center-align"> Amount 2</th>
         <td mat-cell *matCellDef="let element" class="center-align"> {{element.amount2}} </td>
      </ng-container>
      <ng-container matColumnDef="amount3">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="center-align"> Amount 3</th>
         <td mat-cell *matCellDef="let element" class="center-align"> {{element.amount3}} </td>
      </ng-container>
      <ng-container matColumnDef="amount4">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="center-align"> Amount 4</th>
         <td mat-cell *matCellDef="let element" class="center-align"> {{element.amount4}} </td>
      </ng-container>
      <ng-container matColumnDef="amount5">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="center-align"> Amount 5</th>
         <td mat-cell *matCellDef="let element" class="center-align"> {{element.amount5}} </td>
      </ng-container>
      <ng-container matColumnDef="amount6">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="center-align"> Amount 6</th>
         <td mat-cell *matCellDef="let element" class="center-align"> {{element.amount6}} </td>
      </ng-container>
      <ng-container matColumnDef="amount7">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="center-align"> Amount 7</th>
         <td mat-cell *matCellDef="let element" class="center-align"> {{element.amount7}} </td>
      </ng-container>
      <ng-container matColumnDef="amount8">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="center-align"> Amount 8</th>
         <td mat-cell *matCellDef="let element" class="center-align"> {{element.amount8}} </td>
      </ng-container>
      <ng-container matColumnDef="amount9">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="center-align"> Amount 9 Column Name</th>
         <td mat-cell *matCellDef="let element" class="center-align"> {{element.amount9}} </td>
      </ng-container>
      <ng-container matColumnDef="amount10">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="center-align"> Amount 10</th>
         <td mat-cell *matCellDef="let element" class="center-align"> {{element.amount10}} </td>
      </ng-container>
      <tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
      <tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
   </table>
<mat-paginator [pageSizeOptions]="[5, 10, 25, 100]"></mat-paginator>
  </div>

和CSS：

table{
  width:100%;
}
.mat-header-row {
  background-color: #3F51B5;
  color: white;
  font-weight: bold;
}

.mat-header-cell {
  color: white;
  font-weight: bold;
  border-right: solid 0.5px white;
}
.mat-row:nth-child(odd) {
  background-color: white;
}

.mat-row:nth-child(even) {
  background-color: #D3D3D3;
}
.mat-cell{
  border-right: solid 0.5px black;
}
.center-align.th {
  display: flex !important;
  justify-content: center !important;
  padding-left: 18px !important;
}
.center-align.td {
  display: flex !important;
  justify-content: center !important;
}
.left-align.th {
  padding-right: 18px !important;
}

然后列适合内容,但我为中心内容和每列的标题所做的事情不再有效.

最佳答案 我最终想到了这一点.如果其他人想知道你可以在这里看到答案：

基本上我在html中使用table,th和td代替mat-table,mat-h​​eader-cell和mat-cell元素：

<div class="mat-elevation-z8">
<table mat-table [dataSource]="dataSource"  matSort>
      <ng-container matColumnDef="name">
         <th mat-header-cell *matHeaderCellDef mat-sort-header class="left-align-header" > Name </th>
         <td mat-cell *matCellDef="let element" class="left-align-cell"> {{element.name}} </td>
      </ng-container>
      <ng-container matColumnDef="position">
         <th mat-header-cell *matHeaderCellDef mat-sort-header> Position </th>
         <td mat-cell *matCellDef="let element"> {{element.position}} </td>
      </ng-container>
      <ng-container matColumnDef="amount">
         <th mat-header-cell *matHeaderCellDef mat-sort-header> Amount</th>
         <td mat-cell *matCellDef="let element"> {{element.amount}} </td>
      </ng-container>
      <ng-container matColumnDef="amount2">
         <th mat-header-cell *matHeaderCellDef mat-sort-header> Amount 2</th>
         <td mat-cell *matCellDef="let element"> {{element.amount2}} </td>
      </ng-container>
      <ng-container matColumnDef="amount3">
         <th mat-header-cell *matHeaderCellDef mat-sort-header> Amount 3</th>
         <td mat-cell *matCellDef="let element"> {{element.amount3}} </td>
      </ng-container>
      <ng-container matColumnDef="amount4">
         <th mat-header-cell *matHeaderCellDef mat-sort-header> Amount 4</th>
         <td mat-cell *matCellDef="let element"> {{element.amount4}} </td>
      </ng-container>
      <ng-container matColumnDef="amount5">
         <th mat-header-cell *matHeaderCellDef mat-sort-header> Amount 5</th>
         <td mat-cell *matCellDef="let element"> {{element.amount5}} </td>
      </ng-container>
      <ng-container matColumnDef="amount6">
         <th mat-header-cell *matHeaderCellDef mat-sort-header> Amount 6</th>
         <td mat-cell *matCellDef="let element"> {{element.amount6}} </td>
      </ng-container>
      <ng-container matColumnDef="amount7">
         <th mat-header-cell *matHeaderCellDef mat-sort-header> Amount 7</th>
         <td mat-cell *matCellDef="let element"> {{element.amount7}} </td>
      </ng-container>
      <ng-container matColumnDef="amount8">
         <th mat-header-cell *matHeaderCellDef mat-sort-header> Amount 8</th>
         <td mat-cell *matCellDef="let element"> {{element.amount8}} </td>
      </ng-container>
      <ng-container matColumnDef="amount9">
         <th mat-header-cell *matHeaderCellDef mat-sort-header> Amount 9 Column Name</th>
         <td mat-cell *matCellDef="let element"> {{element.amount9}} </td>
      </ng-container>
      <ng-container matColumnDef="amount10">
         <th mat-header-cell *matHeaderCellDef mat-sort-header> Amount 10</th>
         <td mat-cell *matCellDef="let element"> {{element.amount10}} </td>
      </ng-container>
      <tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
      <tr mat-row *matRowDef="let row; columns: displayedColumns;" ></tr>
   </table>
<mat-paginator [pageSizeOptions]="[5, 10, 25, 100]"></mat-paginator>
  </div>

将table-overview-example.css设置为

table{
  width:100%;
}
.mat-header-row {
  background-color: #3F51B5;
  color: white;
  font-weight: bold;
}

.mat-header-cell {
  color: white;
  font-weight: bold;
  border-right: solid 0.5px white;
}

.mat-row:nth-child(odd) {
  background-color: white;
}

.mat-row:nth-child(even) {
  background-color: #D3D3D3;
}
.mat-cell{
  border-right: solid 0.5px black;
}

并将styles.css设置为

@import '~@angular/material/prebuilt-themes/deeppurple-amber.css';

    body { 
      font-family: Roboto, Arial, sans-serif;
      margin: 0;
    }

    .basic-container {
      padding: 30px;
    }

    .version-info {
      font-size: 8pt;
      float: right;
    }

    .mat-sort-header-container{
      justify-content: center !important;
       padding-left: 18px !important; /* Allow for sort icon*/
    } 

    .mat-cell{
       text-align: center;
     } 

     .left-align-cell.mat-cell{
       text-align: left;
     }

     .left-align-header>.mat-sort-header-container{
      justify-content: flex-start !important;
      padding-left:0px !important;
    }
