Column Pinning Feature Guide

Column pinning is a cool feature that lets users pin (freeze) columns to the left or right of the table. Pinned columns will not scroll horizontally with the rest of the columns so that they always stay visible to the user.

Enable Column Pinning

Column pinning can simply be enabled by setting the enableColumnPinning table option to true.

const table = useMantineReactTable({
  data,
  columns,
  enableColumnPinning: true,
});

Pin (Freeze) Columns By Default

Columns can start out pinned in your table by setting the columnPinning states in either initialState or state.

const table = useMantineReactTable({
  data,
  columns,
  enableColumnPinning: true,
  initialState: {
    columnPinning: {
      left: ['email'], //pin email column to left by default
      right: ['mrt-row-actions'], //pin built-in row actions display column to right by default
    },
  },
});
