    Sounds like whatever typing information you are using is incorrect. If you aren't using any specific typing information then yes, you probably would get that error since the settings object is just a plain Javascript object and can be extended any way required by the extensions such as FixedColumns.

    If you can't disable that warning, I guess the only option would be to extend the settings object's definition.

    How can we extend the Settings objects. I couldn't find any sample for that.

    Its just an object so you could use:

    $.fn.dataTable.models.oSettings.myCustomProperty = ...;
    

    However, I would imagine TypeScript won't pick that up. You would probably need to do a bit of declaration merging - but we don't currently publish TypeScript definitions for DataTables. There have been a few thirdparty attempts that you might be able to build on though.
