| `class` | String or Array | Class name (or array of class names) to add to `<th>` **and** `<td>` in the column. |

| `formatter` | String or Function | A formatter callback function or name of a method in your component, can be used instead of (or in conjunction with) scoped field slots. The formatter will be called with the syntax `formatter(value, key, item)`. Refer to [Custom Data Rendering](#custom-data-rendering) for more details. |

| `sortable` | Boolean | Enable sorting on this column. Refer to the [Sorting](#sorting) Section for more details. |

| `sortByFormatted` | Boolean or Function | Sort the column by the result of the field's `formatter` callback function when set to `true`. Default is `false`. Boolean has no effect if the field does not have a `formatter`. Optionally accepts a formatter function _reference_ to format the value for sorting purposes only. Refer to the [Sorting](#sorting) Section for more details. |

| `filterByFormatted` | Boolean or Function | Filter the column by the result of the field's `formatter` callback function when set to `true`. Default is `false`. Boolean has no effect if the field does not have a `formatter`. Optionally accepts a formatter function _reference_ to format the value for filtering purposes only. Refer to the [Filtering](#filtering) section for more details. |

| `tdClass` | String or Array or Function | Class name (or array of class names) to add to `<tbody>` data `<td>` cells in the column. If custom classes per cell are required, a callback function can be specified instead. The function will be called as `tdClass(value, key, item)` and it must return an `Array` or `String`. |
