如何从 Angular Material 5 Mat-Table（Angular Material Table）导出 Excel 文件？

Question

我是 Angular 新手，使用 Angular 材料 5 mat-table 并尝试将表格导出到 excel 文件中。我已经使用 SheetJS XLSX 包。

下面是我的代码：

    <mat-paginator [pageSizeOptions]="[5, 10, 25, 100]"></mat-paginator>
  </div>

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',
   'FirstName','LastName','Email','Role','EmployeeRoleFrom','VendorID',
   'VendorNameCompany','StaffID','Source','HireDate','HireType','EnteredDate',
  'FloorDate','SiteLocation','EmployeeContractorID','TransferFrom','Notes','Status',
  ];  
 
  dataSource = new MatTableDataSource();   
    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
    this.dataSource.filter = filterValue;
  }
 
tableDataSource(){
 this.workflowService.GetUploadDocData().subscribe(
      data => {
        this.dataSource.data = data ;
       
      }  
    );
}

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');     
} 
 
}

我正在使用 npm i XLSX 并遇到一些错误。

错误：

错误范围 (0)：A1:A0

[object Error]{description: "Bad range (...", message: "Bad range (...", name: "Error", ngDebugContext: Object {...}, stack: "Error:糟糕……”}

这里有什么问题？

有没有其他方法可以从 Angular Material Table 中导出 excel，我的表格也需要分页。

Answer 1

SheetJS XLSX 与 Angular Material 5 及更高版本不兼容，因为它读取表格标签，从材料 5 开始使用 mat-table。

Answer 2

为时已晚，但我尝试... 我发现了同样的问题并以这种方式修复： 从

更改 HTML 标记

<mat-table...>...</mat-table> 到 <table mat-table...>...</table>

<mat-header-cell ...>...</mat-header-cell> 到 <th mat-header-cell....>...</th>

<mat-cell...>...</mat-cell> 到 <td mat-cell ...>...</td>

就是这样，XLSX 不识别材质标签，而是识别材质属性。
