Table.component.ts:
import { Component, OnInit, ViewChild, ChangeDetectorRef,ElementRef} from '@angular/core';
import {MatPaginator, MatSort, MatTableDataSource} from '@angular/material';
import { WorkflowService } from "../workflow.service";
import { HttpClient } from '@angular/common/http';
import {DataSource} from '@angular/cdk/collections';
import * as XLSX from 'xlsx/xlsx';
@Component({
selector: 'app-table-doc',
templateUrl: './table-doc.component.html',
styleUrls: ['./table-doc.component.css']
})
export class TableDocComponent implements OnInit {
@ViewChild('TABLE') table: ElementRef;
@ViewChild(MatPaginator) paginator: MatPaginator;
@ViewChild(MatSort) sort: MatSort;
displayedColumns = ['MSID','MSPW','MSRequsest','ClassID','ClassName',

constructor( private http:HttpClient,private workflowService : WorkflowService,private changeDetectorRefs: ChangeDetectorRef) {

ngOnInit() {
this.tableDataSource();
}
ngAfterViewInit() {
this.dataSource.paginator = this.paginator;
this.dataSource.sort = this.sort;
}
applyFilter(filterValue: string) {
filterValue = filterValue.trim(); // Remove whitespace
filterValue = filterValue.toLowerCase(); // Datasource defaults to lowercase matches

ExportTOExcel()
{
const ws:XLSX.WorkSheet=XLSX.utils.table_to_sheet(this.table.nativeElement);
const wb:XLSX.WorkBook = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(wb, ws, 'Sheet1');
console.log(this.table.nativeElement);
/* save to file */
XLSX.writeFile(wb, 'SheetJS.xlsx');
}
}
I am using npm i XLSX and getting some error.
ERROR:
Bad range (0): A1:A0
[object Error]{description: "Bad range (...", message: "Bad range (...", name: "Error", ngDebugContext: Object {...}, stack: "Error: Bad ..."}
what is wrong here?
is there any other way to export excel from Angular Material Table, I also need the pagination for my table.
回答1:
SheetJS XLSX is not compatible with Angular Material 5 & above because it reads table tag where as from material 5 on wards the mat-table is used.
回答2:
Too late, but I try... I found the same problem and fixed this way: Change HTML tags from
<mat-table...>...</mat-table> to <table mat-table...>...</table>
<mat-header-cell ...>...</mat-header-cell> to <th mat-header-cell....>...</th>
<mat-cell...>...</mat-cell> to <td mat-cell ...>...</td>
That's all, XLSX not recognize material tags, but the material attributes.
