The updated **[cell](https://datatables.net/reference/api/cell())**, **[row](https://datatables.net/reference/api/row())**, and previous value in that cell are passed as arguements. This function can return a jQuery promise object. In such case, the table will be redraw when the promise is resolved.
 **inputCss** _(optional)_| string | none |```'my-css-class'```| A CSS class that will be applied to the input field
 **columns** _(optional)_| array | All columns |```[0,1,3,4]```| An array of column indexes defining the columns that you want to be editable.
 **allowNulls** _(optional)_| object | false | ```{ "columns": [4], "errorClass":"my-error"}``` | Determines which columns should allow null values to be entered and what CSS to apply if user input fails validation. If **errorClass** is null a default error class will be applied.
