我是 Angular 新手，使用 Angular material 5 mat-table 并尝试将表格导出到 excel 文件中。我使用了 SheetJS XLSX包。
下面是我的代码：
Table.component.html：
<mat-table #table [dataSource]="dataSource" matSort>
<!-- ID Column -->
<!--<ng-container matColumnDef="ID">
<mat-header-cell *matHeaderCellDef mat-sort-header> UserID </mat-header-cell>
<mat-cell *matCellDef="let row"> {{row.UserID}} </mat-cell>
</ng-container>-->
<!-- Progress Column -->
<ng-container matColumnDef="MSID">
<mat-header-cell *matHeaderCellDef mat-sort-header> MSID </mat-header-cell>
<mat-cell *matCellDef="let row"> {{row.MSID}} </mat-cell>
</ng-container>
<ng-container matColumnDef="MSPW">
<mat-header-cell *matHeaderCellDef mat-sort-header> MS Password </mat-header-cell>
<mat-cell *matCellDef="let row"> {{row.MSPW}} </mat-cell>
</ng-container>
<ng-container matColumnDef="MSRequsest">

</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: Bad .. ."}
这里有什么问题？
有没有其他方法可以从 Angular Material Table 导出 excel，我还需要我的表的分页。
