Sometimes we need to display more than one mat-table in a same component in Angular.
That’s not a problem, we can add multiple mat-table in a single component without any problems, but to add sorting and paginator to the mat-table we need to give unique matSort and mat-paginator template reference variables.
Let’s go through an example to understand it further.
We will take the employee table example
<table
mat-table
[dataSource]="dataSource"
class="mat-elevation-z8"
matSort
#empTbSort="matSort"
>
</table>
First we should add matSort
directive to the mat-table.
And then add a template reference variable to matSort
directive.
#empTbSort="matSort"
Now get matSort
directive reference in the component ts file using @ViewChild
And assign it to mat-table data source.
@ViewChild('empTbSort') empTbSort = new MatSort();
ngAfterViewInit() {
this.dataSource.sort = this.empTbSort;
}
Similarly if we have multiple tables in the same component, we need to give unique template reference variable to each matSort directive.
<table
mat-table
[dataSource]="dataSource"
class="mat-elevation-z8"
matSort
#empTbSort="matSort"
>
</table>
<table
mat-table
[dataSource]="dataSourceWithObjectColumn"
class="mat-elevation-z8"
matSort
#empTbSortWithObject="matSort"
>
</table>
And in the component ts file
@ViewChild('empTbSort') empTbSort = new MatSort();
@ViewChild('empTbSortWithObject') empTbSortWithObject = new MatSort();
ngAfterViewInit() {
this.dataSource.sort = this.empTbSort;
this.dataSourceWithObjectColumn.sort = this.empTbSortWithObject;
}
That’s it, the sorting work perfectly for each mat-table in the component.
Similarly we need to add mat-paginator as well.
<table
mat-table
[dataSource]="dataSource"
class="mat-elevation-z8"
matSort
#empTbSort="matSort"
>
</table>
<mat-paginator
#paginatorFirst
[pageSizeOptions]="[2, 4, 6]"
showFirstLastButtons
></mat-paginator>
<table
mat-table
[dataSource]="dataSourceWithObjectColumn"
class="mat-elevation-z8"
matSort
#empTbSortWithObject="matSort"
>
</table>
<mat-paginator
#paginatorSecond
[pageSizeOptions]="[2, 4, 6]"
showFirstLastButtons
></mat-paginator>
And in component ts file assign mat-paginator to the mat-table data source as shown below.
@ViewChild('paginatorFirst') paginatorFirst: MatPaginator;
@ViewChild('paginatorSecond') paginatorSecond: MatPaginator;
ngAfterViewInit() {
this.dataSource.paginator = this.paginatorFirst;;
this.dataSourceWithObjectColumn.paginator = this.paginatorSecond;;
}
