我正在尝试使用 MatSort 模块对 Angular Material 中的表格进行排序，但出现此错误：

Property 'sort' has no initializer and is not definitely assigned in the constructor.

这是我的 ts 文件：

import { Component, OnInit, ViewChild } from '@angular/core';
import { Personal } from 'src/app/models/personal.model';
import { PersonalService } from 'src/app/services/personal.service';
import { MatTableDataSource } from '@angular/material/table';
import { MatPaginatorModule } from '@angular/material/paginator'; 
import { MatSort, MatSortModule, MatSortHeader } from '@angular/material/sort'

@Component({
  selector: 'app-personal-list',
  templateUrl: './personal-list.component.html',
  styleUrls: ['./personal-list.component.css']
})

export class PersonalListComponent implements OnInit {
  personals?: Personal[];
  currentPersonal?: Personal; …
