在使用Ag Grid时,可以通过定义自定义的头部渲染器来替代默认的头部渲染器。下面是一个使用Angular的代码示例:
custom-header-renderer.component.ts
:import { Component } from '@angular/core';
import { IHeaderAngularComp } from 'ag-grid-angular';
@Component({
selector: 'app-custom-header-renderer',
template: `
{{ params.displayName }}
`,
styles: [
`
.custom-header {
font-weight: bold;
}
.custom-header-icons {
display: flex;
justify-content: flex-end;
}
`,
],
})
export class CustomHeaderRendererComponent implements IHeaderAngularComp {
public params: any;
agInit(params: any): void {
this.params = params;
}
}
app.component.ts
:import { Component } from '@angular/core';
import { ColDef } from 'ag-grid-community';
@Component({
selector: 'app-root',
template: `
`,
})
export class AppComponent {
public rowData: any[];
public columnDefs: ColDef[];
constructor() {
this.rowData = [
{ make: 'Toyota', model: 'Celica', price: 35000 },
{ make: 'Ford', model: 'Mondeo', price: 32000 },
{ make: 'Porsche', model: 'Boxster', price: 72000 },
];
this.columnDefs = [
{
headerName: 'Make',
field: 'make',
headerComponentFramework: CustomHeaderRendererComponent,
},
{ headerName: 'Model', field: 'model' },
{ headerName: 'Price', field: 'price' },
];
}
}
app.module.ts
:import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AgGridModule } from 'ag-grid-angular';
import { AppComponent } from './app.component';
import { CustomHeaderRendererComponent } from './custom-header-renderer.component';
@NgModule({
declarations: [AppComponent, CustomHeaderRendererComponent],
imports: [BrowserModule, AgGridModule.withComponents([CustomHeaderRendererComponent])],
providers: [],
bootstrap: [AppComponent],
})
export class AppModule {}
以上代码示例演示了如何定义和使用自定义的头部渲染器组件CustomHeaderRendererComponent
来替代默认的头部渲染器。在这个示例中,自定义的头部渲染器显示列的名称,并添加了排序和过滤的图标。
