**Custom-react-table** is based on <code>React-Table v7</code>: collection of hooks for **building powerful tables and datagrid experiences**. These hooks are lightweight, composable, and ultra-extensible, but **do not render any markup or styles for you*

// Various functions pulled from the internal react-table utils package - useful
// when pulling hooks from the main repo before changing them.

  for (let i = 0; i < args.length; i += 1) {
    if (typeof args[i] !== 'undefined') {
      return args[i]
    }
