如何使用AG-Grid、Angular和TypeScript动态设置列ColSpan

npm install ag-grid ag-grid-angular

import { Component, OnInit } from '@angular/core';
import { AgGridModule } from 'ag-grid-angular';

export class MyComponent implements OnInit {
  columnDefs = [
    { headerName: 'Name', field: 'name' },
    { headerName: 'Age', field: 'age' },
    { headerName: 'Country', field: 'country' },
    // 其他列定义...
  ];

  rowData = [
    { name: 'John', age: 25, country: 'USA' },
    { name: 'Jane', age: 30, country: 'Canada' },
    { name: 'Bob', age: 35, country: 'UK' },
    // 其他数据...
  ];

  // 其他组件代码...
}

<ag-grid-angular
  style="width: 500px; height: 300px;"
  class="ag-theme-alpine"
  [columnDefs]="columnDefs"
  [rowData]="rowData"
></ag-grid-angular>

{ 
  headerName: 'Name', 
  field: 'name', 
  cellRenderer: 'customCellRenderer' 
}

import { ICellRendererAngularComp } from 'ag-grid-angular';

@Component({
  selector: 'app-custom-cell-renderer',
  template: `
    <div [style.gridColumn]="colSpan">{{ params.value }}</div>
  `,
})
export class CustomCellRendererComponent implements ICellRendererAngularComp {
  params: any;
  colSpan: number;

  agInit(params: any): void {
    this.params = params;
    // 根据需要设置ColSpan的值
    this.colSpan = 2;
  }

  refresh(params: any): boolean {
    return false;
  }
}

import { NgModule } from '@angular/core';
import { AgGridModule } from 'ag-grid-angular';
import { CustomCellRendererComponent } from './custom-cell-renderer.component';

@NgModule({
  declarations: [CustomCellRendererComponent],
  imports: [AgGridModule.withComponents([CustomCellRendererComponent])],
})
export class MyModule {}
