How to clone a shape in Ingeo print layout?

Question

GIS

The print layout has an IInPictureGridFigure. I want to programmatically create another grid with the same style as the one already in the layout. Ideally, of course, I would generally clone the existing one, but so far I have not found such an opportunity. So far I'm doing this:
Code:

var newTableFigure = MyLayoutWindow.Figures.Add(TInPictureFigureType.inftMap) as IInPictureGridFigure;
                newTableFigure .Bottom = existTable.Bottom;
                newTableFigure .Width = existTable.Bottom;
                newTableFigure .GridFormat = existTable.GridFormat;
                newTableFigure .ColFormat = existTable.ColFormat;
                 newTableFigure .RowFormat = existTable.RowFormat;

But unfortunately RowFormat/ColFormat/GridFormat are not set this way.
I tried creating like this:

orgTableFigure.GetFormat(j, -1).Size[TInGridFormatKind.ingfFont] = organizationTable.GetFormat(-1, 0).Size[TInGridFormatKind.ingfColWidth];

But unfortunately Ingeo crashes with an error:

Destructive by itself (Exception from HRESULT: 0x8000FFFF (E_UNEZPECTED))

How can the problem be solved?
This is how the error does not appear:

newTableFigure .GetFormat(j, -1).Size[TInGridFormatKind.ingfColWidth] = 250; //existFigure .GetFormat(j, -1).Size[TInGridFormatKind.ingfColWidth];
                                newTableFigure .GetFormat(j, -1).Update();

But unfortunately the column width size is not set.
