$table->primary('column');
// Creates a dual primary key$table->primary(['first', 'last']);
$table->unique('column');
$table->unique('column', 'key_name');
// Creates a dual unique index$table->unique(['first', 'last']);
$table->unique(['first', 'last'], 'key_name');
$table->index('column');
$table->index('column', 'key_name');
// Creates a dual index$table->index(['first', 'last']);
$table->index(['first', 'last'], 'key_name');
$table->dropPrimary('table_column_primary');
$table->dropUnique('table_column_unique');
$table->dropIndex('table_column_index');

$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
