Method Summary
`void`	`add(DataTableRow row)` Adds the given `DataTableRow` to the table.
`int`	`getColumnIndex(java.lang.String name)` Returns the column index of the column with the given name.
`java.lang.String`	`getColumnName(int i)` Returns the name of the i-th column.
`double`	`getColumnWeight(int column)` Returns the weight of the column or Double.NaN if no weight is available.
