By default, Handsontable treats all cell values as string type. This is because <textarea>
returns a string as its value.
In many cases you will prefer cell values to be treated as number type. This allows to format
numbers nicely and sort them correctly.
To trigger the Numeric cell type, use the option type: 'numeric' in columns array
or
cells function.
Numeric cell type uses Numbro.js as the formatting library. Head over to their website to learn about the formatting syntax.
To use number formatting style valid for your language (i18n), load language definition to Numbro.js. See "Languages" section in Numbro.js docs for more info.
