Material Table Filter (matTableFilter Directive)
Provides filtering support for @angular/material tables. Table filtering is done by using the directive matTableFilter. This project is inspired by Hibernate's example api. By employing this directive you will end up with having
- Less code, less complicated logic for filtering
- Default debounce support
- Being able to filter nested objects no matter how deep the properties are
Installation
npm install mat-table-filter
NOTE: Angular versions older than Angular 8 should install mat-table-filter@1.2.5
npm install mat-table-filter@1.2.5
For Angular versions between 8-13 (inclusive), please install mat-table-filter@10.2.4
npm install mat-table-filter@10.2.4
After installing mat-table-filter import MatTableFilterModule in your ngModule
import { MatTableFilterModule } from 'mat-table-filter';
@NgModule({
imports: [
...
MatTableFilterModule
],
]})
Usage
A datasource of a simple array won't work. In order to use matTableFilter, your table's datasource must be created as MatTableDataSource, see the example below.
dataSource = new MatTableDataSource(ELEMENT_DATA);
- Add matTableFilter directive as a property to your material table.
<table mat-table matTableFilter [dataSource]="dataSource" ...>
- Keep an example object of the same type with your items in your table.
- Bind the exampleObject to the exampleEntity property of the matTableFilter directive
<table mat-table matTableFilter [dataSource]="dataSource" [exampleEntity]="exampleObject"...>
That's all. When you populate the exampleObject's properties, the filter will automatically work just fine with the default debounce support. You can change the debounce time also.
