/**
 * Rendering methods using the Javascript Intl API. This is supported by IE11,
 * Edge, Chrome, Firefox and Safari 10+. Any browser that does not support the
 * Intl will simply show the unformatted data to the end user.
 *
 * The great advantage of using these methods is that your table's data will
 * automatically be shown to your end user formatted for their locale. For
 * example a date might be formatted as "m/d/yyyy" in the US, while in France
 * it would show as "dd/mm/yyyy".
 *
 * Two rendering methods are available:
 *
 * * `intlNumber` which will format numbers.
 * * `intlDateTime` which formats date times.
 *
 * Both optionally takes two arguments:
 *
 * 1. [Optional] Locale or array of locales
 * 2. [Optional] Formatter options
 *
 * For the supported options please see the MDN documentation for
 * [DateTimeFormat](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/DateTimeFormat) and
 * [NumberFormat](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/NumberFormat).
