Remarks
The CreateDataTable method creates an empty data table. The number of columns in a data table is the same as the number of columns in the specified range. The first row of the specified cell range defines column names if the rangeHasHeaders parameter is set to true. If the stringColumnType parameter is true, all columns in a resulting data table will be of the string type.
The first row in the specified range is used to determine column data types if the rangeHasHeaders and the stringColumnType parameters are set to false.
If the first row in a specified range contains column names (the rangeHasHeaders parameter for the CreateDataTable method is set to true), the second row is used to determine the column data types.
To determine the column data type for the resulting data table, the CellValue.Type of data contained in a cell is used.
