Getting Values

Introduction

A cell’s value comes from its column’s field — the key the column reads from each row record. Renderers receive that resolved value on their params as value, which is what they turn into DOM.

const columns = [
  { field: 'name', header: 'Name' },     // reads row.name
  { field: 'revenue', header: 'Revenue' } // reads row.revenue
];

A custom renderer sees the value like this:

const renderer = {
  render(params) {
    params.value; // the cell's resolved value
  }
};
