Row Numbers Guide - Material React Table V2 Docs

Row Numbers Feature Guide

Material React Table has an easy to implement row number features. There are two row number modes that you can enable. You can have row numbers that are associated with the data in the table (original mode), or you can have row numbers that are just statically part of the table (static mode).

2	'original' \| 'static'	'original'

Enable Row Numbers (Static Mode)

In the default rowNumberDisplayMode (static), row numbers are just a static part of the table in their own column. They act like the row numbers in an excel spreadsheet. Sorting and filtering will not affect the row numbers.

This example is written for MRT V2.

If your app is still using MRT V1, either Upgrade to MRT V2 or use the V1 Docs instead. (useMaterialReactTable only exists in V2)

Enable Row Numbers (Original Mode)

Alternatively, use the "original" rowNumberDisplayMode to have row numbers linked to the original index of the data array. This means that when you search or filter, the same row numbers will stay with the same rows as data is sorted and filtered.
