It seems like $row->getStyle() can be null; however, merge() does not accept null, maybe add an additional type check?
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Unless you are absolutely sure that the expression can never be null because of
other conditions, we strongly recommend to add an additional type check to your
code:


/** @return stdClass|null */
function mayReturnNull() { }

function doesNotAcceptNull(stdClass $x) { }

// With potential error.
function withoutCheck() {
    $x = mayReturnNull();
    doesNotAcceptNull($x); // Potential error here.
}

// Safe - Alternative 1
function withCheck1() {
    $x = mayReturnNull();
    if ( ! $x instanceof stdClass) {
        throw new \LogicException('$x must be defined.');
    }
    doesNotAcceptNull($x);
}

// Safe - Alternative 2
function withCheck2() {
    $x = mayReturnNull();
    if ($x instanceof stdClass) {
        doesNotAcceptNull($x);
    }
}
