 $tables = array_column($tables, 'Tables_in_new_b_web');
 $columns = ['email', 'user_name', 'nick_name', 'first_name', 'last_name'];
 // dd(Schema::getConnection());
 foreach ($tables as $key => $value) {
  foreach ($columns as $k => $v) {

Schema::getColumnListing('user');
Schema::hasColumn($table, $column_name)
