Translate datatable to Spanish

Hello,
I am trying to translate my datatable to Spanish and I look into several options.
I placed the following in the language option:

language: {
        url: 'dataTables.spanish.json'
},

language: {
        url: '//cdn.datatables.net/plug-ins/1.10.24/i18n/Spanish_Mexico.json'
},

Neither of these worked, and plugging in the JSON in this page worked only partially.
