how should I change Material Table titles using transloco i18n(internationalization) liabrary for pagination and page range, next , previous buttons?

want to show titles using i18n Above is the image for showing titles 'items per page'

First, create a custom MatPaginatorIntl that uses Transloco for translation.

import { MatPaginatorIntl } from '@angular/material/paginator';
import { TranslocoService } from '@ngneat/transloco';

export class TranslocoPaginatorIntl extends MatPaginatorIntl {
  constructor(private _translocoService: TranslocoService) {
    super();

    this._translocoService.selectTranslateObject('table').subscribe((translation) => {
      this.itemsPerPageLabel = translation.itemsPerPage;
      this.nextPageLabel = translation.nextPage;
      this.previousPageLabel = translation.previousPage;
      this.firstPageLabel = translation.firstPage;
      this.lastPageLabel = translation.lastPage;

      this.getRangeLabel = (page, pageSize, length) => {
        if (length === 0 || pageSize === 0) {
          return `0 ${translation.of} ${length}`;
        }
        length = Math.max(length, 0);
        const startIndex = page * pageSize;
        const endIndex =
          startIndex < length ? Math.min(startIndex + pageSize, length) : startIndex + pageSize;
        return `${startIndex + 1} - ${endIndex} ${translation.of} ${length}`;
      };

      // This is required to update the paginator labels after the translation is loaded
      this.changes.next();
    });
  }
}

In this code, TranslocoPaginatorIntl is a custom MatPaginatorIntl that uses Transloco for translations. It subscribes to the translations for the 'table' key and updates the labels accordingly.

Then, you need to provide TranslocoPaginatorIntl in your module:

import { MatPaginatorIntl } from '@angular/material/paginator';
import { TranslocoModule, TranslocoService } from '@ngneat/transloco';
import { TranslocoPaginatorIntl } from './your/path/to/transloco-paginator-intl';

@NgModule({
  imports: [
    // ... other modules
    TranslocoModule,
  ],
  providers: [
    // ... other providers
    {
      provide: MatPaginatorIntl,
      useClass: TranslocoPaginatorIntl,
      deps: [TranslocoService],
    },
  ],
  // ... other properties
})
export class YourModule {}

In this code,

{
  provide: MatPaginatorIntl,
  useClass: TranslocoPaginatorIntl,
  deps: [TranslocoService],
},

tells Angular to use TranslocoPaginatorIntl instead of the default MatPaginatorIntl.

NOTE:
Remember to replace 'table' with the actual key in your translation files, and replace the translation keys (itemsPerPage, nextPage, etc.) with the actual keys in your translation files. My i18n setup is for en-us & zh-tw. The i18n json files sample are as follows:

en-us.json

{
  "table": {
    "search": "Search",
    "keywords": "Keywords",
    "itemsPerPage": "Items per page",
    "nextPage": "Next page",
    "previousPage": "Previous page",
    "firstPage": "First page",
    "lastPage": "Last page",
    "of": "of",
    "noData": "No data",
  }
}

zh-tw.json:

{
  "table": {
    "search": "搜尋",
    "keywords": "關鍵字",
    "itemsPerPage": "每頁數量",
    "nextPage": "下一頁",
    "previousPage": "上一頁",
    "firstPage": "第一頁",
    "lastPage": "最後一頁",
    "of": "從",
    "noData": "沒有資料",
  }
}
