我需要修复标题上的内容。我的意思是，一旦您滚动经过标题，它就会保留在屏幕上，直到下一个表格。我尝试添加position:sticky和top:0，但它仍然滚动过去。我查找了可能妨碍的溢出，但找不到任何溢出。还有其他方法可以做到这一点吗？
<tr>
<ng-container *ngFor="let year of years; let yearIdx=index;">
<th class="table-header" [ngClass]="{'odd': yearIdx % 2 == 1}">
{{year}}
</th>
</ng-container>
</tr>
<ng-container
*ngFor="let equip of getEquip(category); let first=first; let last=last; let index=index;">
<tr>
<ng-container *ngFor="let year of years; let yearIdx = index;">
<td class="table-contents equip-cell">
<ng-container>
<i class="material-icons equip-present">check_circle</i>

*ngIf="getItem(equip.equipment) > 0 && getItems(equip.equipment) < 1">
{{getItem(equip.equipment) | percent: '1.1-1':
'pt'}}
</span>
</ng-container>
<ng-container *ngIf="this.filter.grouping === 'VERSION'">
