Generates a hyperlink that links to the sort action to sort by the specified attribute.
Based on the sort direction, the CSS class of the generated hyperlink will be appended
with "asc" or "desc".
@param string $attribute the attribute name by which the data should be sorted by.
@param array $options additional HTML attributes for the hyperlink tag.
There is one special attribute `label` which will be used as the label of the hyperlink.
If this is not set, the label defined in [[attributes]] will be used.
If no label is defined, [[\yii\helpers\Inflector::camel2words()]] will be called to get a label.
Note that it will not be HTML-encoded.
@return string the generated hyperlink
@throws InvalidConfigException if the attribute is unknown
