## Field options

Available options

- [name](#-name)
- [sortField](#-sortField)
- [title](#-title)
- [titleClass](#-titleClass)
- [dataClass](#-dataClass)
- [callback](#-callback)
- [visible](#-visible)
- [width](#-width)

### # name

- type: _String_

Name of the data field to be display.

### # sortField

- type: _String_

Usually, it will be the same as `name` option. But you can specify different value if
you use different field name when querying data on the serve side, e.g. firstname.

If specified, the field will be marked as sortable. `vuetable` will display appropriate
clickable icon after the field title. `vuetable` will also make a new request to the server
with the `sort=<sortField>` query string appended.

### # title

- type: [_String_, _Function_]

If you would like to specify the title yourself, you can put it in here. Otherwise, `vuetable`
will use the `name` option instead.

You can even put the icon class in the title, see example below

```javascript
//.. example using Semantic UI icon class
{
  name: 'birthdate',
  title: '<i class="orange birthday icon"></i> Birthdate'
}
//
```

_New feature (after v1.6.5)_
You can also define `title` as a function that returns a string. Vuetable will use that returned string to render the title of the column.

```javascript
//.. example using Semantic UI icon class
{
  name: 'birthdate',
  title: () => '<i class="orange birthday icon"></i> Birthdate'
}
//
```

This allow total flexibility and make it possible to make use of external i18n library.

### # titleClass

- type: _String_

The css class you would like to apply for the title of this field.

### # dataClass

- type: _String_

The css class you would like to apply for the data of this field.

### # callback

- type: [_String_, _Function_]

The name of the callback function to be called to allow formatting of the value
to be displayed. See [Callback](Callbacks) section for more info.

### # visible

- type: _Boolean_

Whether this field should be visible or hidden when rendering the table.

### # width _(since v1.7)_

- type: _String_

Specify the width of the column as string, e.g. `600px`. See [Fixed Header](Fixed-Header) section for more info.

## Nested JSON Data

If the JSON data structure contains nested objects, eg:

```json
{
  "links": {
    "pagination": {
      "per_page": 15,
    }
  },
  "data": [
    {
      "id": 1,
      "name": "xxxxxxxxx",
      "email": "xxx@xxx.xxx",
      "group_id": 1,
      "address" {
        "street_address":"123 abc place",
        "city":"townsville",
        "province":"Harbor",
        "country":"Antegria"
      }
    }
      .
      .
      .
    {
      "id": 50,
      "name": "xxxxxxxxx",
      "email": "xxx@xxx.xxx",
      "group_id": 3,
      "address" {
        "street_address":"456 xyz street",
        "city":"cityville",
        "province":"Portia",
        "country":"Norland"
      }
    }
  ]
}
```

In this case, the column names of nested objects can be specified in the following format:

```javascript
let columns = ["name", "email", "address.city", "address.country"];
```
