inlinevirtual

Gets a single cell within the table that is located at the given column offset and row.

Parameters

rowNumber	The unique number of the row where the cell is located.
columnOffset	The zero-based offset of the column of the cell to return.

Returns: Returns an instance of DataObject that is contained in the cell located by the row and column coordinates provided.

Exceptions

ArgumentOutOfRangeException If the given columnOffset is less than zero or greater or equal than the number of columns defined in the table metadata.
