Power Bi将不同表中的列相乘

Question

我遇到这些表的问题。我需要为每个@interface ViewController () { IBOutlet UITableView *viewsTbl; IBOutlet UIButton *addBtn; NSMutableArray *countArr; NSMutableDictionary *dataArr; NSInteger number; } @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; countArr = [NSMutableArray array]; dataArr = [NSMutableDictionary dictionary]; [dataArr setValue:@"" forKey:@"TextFieldOne"]; [dataArr setValue:@"" forKey:@"TextFieldTwo"]; [countArr addObject:dataArr]; // Do any additional setup after loading the view, typically from a nib. } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return countArr.count; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { ViewTableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:@"ViewTableViewCell"]; if (cell == nil) { cell = [[[NSBundle mainBundle] loadNibNamed:@"ViewTableViewCell" owner:self options:nil] objectAtIndex:0]; } if (countArr.count == indexPath.row+1) { cell.buttonPlus.hidden = NO; } else { cell.buttonPlus.hidden = YES; } NSDictionary *dict = countArr[indexPath.row]; cell.txtFldOne.text = dict[@"TextFieldOne"]; cell.txtFldTwo.text = dict[@"TextFieldTwo"]; cell.txtFldTwo.delegate = self; cell.txtFldOne.delegate = self; cell.txtFldOne.tag = indexPath.row; cell.txtFldTwo.tag = indexPath.row+1000; [cell.buttonPlus addTarget:self action:@selector(plusBtnClick) forControlEvents:UIControlEventTouchUpInside]; [cell.buttonMinus addTarget:self action:@selector(minusBtnClick:) forControlEvents:UIControlEventTouchUpInside]; cell.selectionStyle = UITableViewCellSelectionStyleNone; return cell; } - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return 150; } -(void)plusBtnClick { dataArr = [NSMutableDictionary dictionary]; [dataArr setValue:@"" forKey:@"TextFieldOne"]; [dataArr setValue:@"" forKey:@"TextFieldTwo"]; [countArr addObject:dataArr]; [viewsTbl reloadData]; } -(IBAction)minusBtnClick:(id)sender { CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:viewsTbl]; NSIndexPath *indexPath = [viewsTbl indexPathForRowAtPoint:buttonPosition]; NSLog(@"%@",indexPath); [countArr removeObjectAtIndex:indexPath.row]; [viewsTbl reloadData]; if (countArr.count == 0) { addBtn.hidden = NO; viewsTbl.hidden = YES; } else { addBtn.hidden = YES; viewsTbl.hidden = NO; } } -(IBAction)addBtnClick:(id)sender { dataArr = [NSMutableDictionary dictionary]; [dataArr setValue:@"" forKey:@"TextFieldOne"]; [dataArr setValue:@"" forKey:@"TextFieldTwo"]; [countArr addObject:dataArr]; addBtn.hidden = YES; viewsTbl.hidden = NO; [viewsTbl reloadData]; } 计算(af_escalaItem[valor]*af_servprod_criterios[peso])，但我似乎无法做到这一点。

请参阅下面的图片以便更好地理解。

提前谢谢。

如果表格之间的关系设置正确，您可以使用RELATED()函数计算列：

Multiple = RELATED(af_escalaItem[valor]) * RELATED(af_servprod_criterios[peso])

编辑：

由于表之间的关系包含复合键，因此需要使用以下函数来查找peso的值：

Multiple = 
RELATED(af_escalaItem[valor]) * 
CALCULATE(
    VALUES(af_servprod_criterios[peso]),
    FILTER(
        af_servprod_criterios,
        af_avaliacaoItens[af_criterio_id] = af_servprod_criterios[af_criterio_id] &&
        RELATED(af_fornecedorAvalia[af_servprod_id]) = af_servprod_criterios[af_servprod_id]
    )
)

结果：
