Density Toggle Feature Guide

Material React Table includes a density toggle button in the top toolbar by default that lets you toggle between three different density levels. This is a great feature to include to help with accessibility for different user preferences, but it can also easily be disabled if desired.

Default Density

By default, Material React Table will render with a medium comfortable density.

A density toggle is shown by default to let a user change the density to cycle through spacious, comfortable, and compact densities.

When a compact density is set, whitespace is set to nowrap by default to keep the rows as short in height as possible. This can be overridden in the muiTableBodyCellProps styles or sx prop.

Change Default Density

If you want to change the default density, you can set it in either the initialState prop or the state prop.

<MaterialReactTable
  data={data}
  columns={columns}
  initialState={{ density: 'compact' }}
/>

Disable or Hide the Density Toggle

You can change the default density and disable the density toggle itself if you want.

In this example, the density toggle is disabled and a compact density is set by default in the initialState prop.
