Question 1

How to implement server-side pagination with ngx-datatable?

Accepted Answer

Handle page events and bind to external data sources by fetching data from APIs on pagination changes. The documentation provides examples for managing server-side sorting and filtering alongside pagination to keep performance optimal.

Question 2

ngx-datatable vs Angular Material table – which is better?

Accepted Answer

Choose ngx-datatable for performance-critical apps with large datasets due to its virtual DOM and lightweight design. Angular Material table is better if you're deeply integrated into Material Design and prefer a more opinionated, styled component out of the box.

Question 3

Can ngx-datatable handle real-time data updates efficiently?

Accepted Answer

Yes, by updating the bound data array, but for frequent changes, use Angular's change detection strategies to minimize re-renders. The virtual DOM helps, but server-side pagination is recommended for very dynamic data to avoid performance hits.

Question 4

How to customize cell templates in ngx-datatable?

Accepted Answer

Use the expressive template system to define custom HTML in Angular components or inline templates. Refer to the demos for examples on binding data and applying CSS, allowing full control over cell content and styling.

Question 5

Is ngx-datatable responsive for mobile devices?

Accepted Answer

It supports scrolling configs that can be adapted for mobile, but fluid responsiveness often requires additional CSS media queries. The included themes are not fully responsive by default, so extra styling effort is needed for small screens.

Question 6

What are the performance benchmarks for ngx-datatable with 10,000 rows?

Accepted Answer

With virtual DOM enabled, it renders only visible rows, maintaining smooth performance. Community benchmarks show minimal lag, but for optimal results, combine with server-side pagination and efficient data binding to handle extreme datasets.

Question 7

How to add filtering to ngx-datatable?

Accepted Answer

Implement filtering externally by creating input controls, processing the data array, and rebinding it to the table. Since no built-in feature exists, look to community examples or custom Angular pipes for client-side filtering solutions.
