Answer 1

you can do this in two difference way : 1 . If you want use active record you must set property in first model you want to select it and join table with that like:
public $pin;
then when you get data you can access to pin in second table
the second way is you use asArray() that return all off data in both table
$model = News::find()->leftJoin('comment', 'news.id = comment.news_id')->asArray()->all();
then you can use it in your gridview

Answer 2

You should add a getter eg:getCompanyname()n your base model
......
public function attributeLabels()
{
return [
'id' => 'ID',
//'company_id' => 'Company ID',
'emp_name' => 'Emp Name',
'emp_email' => 'Emp Email',
'emp_salery' => 'Emp Salery',
'companyName' => 'Company Name')
];
}
public function getCompany()
{
return $this->hasOne(Company::className(),['id' => 'company_id']);
}
You should add a getter for company name
/*
Getter for company name
*/
public function getCommpanyName() {
return $this->company->name;
}
and in your gridview you should use the new get name (companyName)
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
'companyName',
'emp_name',
'emp_email:email',
'emp_salery',
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
