html:

<ng-container *ngIf="oCode_test1(table.oCode)'">
    <span>{{aaa}}:</span>
</ng-container>
<ng-container *ngIf="oCode_test2(table.oCode)'">
    <span>{{bbb}}:</span>
</ng-container>
<ng-container *ngIf="oCode_test3(table.oCode)'">
    <span>{{ccc}}:</span>
</ng-container>

ts:

  oCode_test1(oCode){
    if(oCode == 'aa' || oCode == 'aa1st' || oCode == 'aah2' ||
       oCode == 'aaq1' || oCode == 'aaq3' || oCode == 'aaq4'){
         return true
       }
       return false
  }

  oCode_test2(oCode){
    if(oCode == 'qq' || oCode == 'qq1st' || oCode == 'qqh2' ||
       oCode == 'qqq1' || oCode == 'qqq3' || oCode == 'qqq4'){
         return true
       }
       return false
  }

  oCode_test3(oCode){
    if(oCode == 'ww' || oCode == 'ww1st' || oCode == 'wwh2' ||
       oCode == 'wwq1' || oCode == 'wwq3' || oCode == 'wwq4'){
         return true
       }
       return false
  }

ts的部分,感觉重复性过高，该怎么优化，3个function有办法合并成一个吗？
