Best Answer

The c type column does not accept an optional argument, hence the error message you get. In order to make your code compilable, replace c with S. The latter is a column type defined by the siunitx package, which, among others accepts the table-format option that you used. In order to get the correct alignment of the numbers, as well as the right column widths, you should also correct the values of table-format according to the contents of the corresponding table columns. In the following example, I have also added @{\extracolsep{\fill}} in order to make sure the table is as wide as the specified width, while the columns are spread evenly:
