Defines columns that show subtotal values.

\*\*What it does:\*\* Shows subtotals - these are columns that show the aggregation of values for a specific attribute pivoting subgroup.

\*\*When it's created:\*\* - Only when you have at least 2 attributes in the columns bucket (pivoting). - Only when you set total for pivoting subgroup (not the leftmost column attribute - then it's grand total). - In the example, total is set for Product x Sales.

\*\*Real example:\*\*

```tsx
|         |        | Brand > Product     |                |
|         |        |---------------------|----------------|
|         |        | GoodData            |                |
|         |        |---------------------|----------------|
|         |        | Panther  | Bear     | Sum A          |
|---------|--------|---------------------|----------------|
| Country | City   | Sales    | Sales    | Sales          |
|---------|--------|----------|----------|----------------|
| USA     | NYC    | 100      | 150      | 250            |
| USA     | LA     | 200      | 250      | 450            |
```

   * Handles case, when pivoting and measures are in rows.
   */ {
    isEmpty: false;
    isTransposed: true;
    totalHeader: IResultTotalHeader;
    attributeDescriptor: IAttributeDescriptor;
}
/**
