Fixed Columns undefined is not a function

[MohamedYakout]

I got this error undefined is not a function through using fixed column, when I add the following option to dtOptions:

.withFixedColumns({
        leftColumns: 1
    });

For more details I asked this Question on stackoverflow, but no correct answer ?

You forgot to add the dataTables.fixedColumns.js file.

@l-lin Thanks, it's working now 👍

Including dataTables.fixedColumns.js from FixedColumns is solution

I have the same error and i have include dataTables.fixedColumns.js and not fix my error

+1 for me; including dataTables.fixedColumns.js doesn't fix; I get a Object doesn't support property or method 'withFixedColumns' error.

I can fix the 1st row / 1st column by doing:

        .withOption("fixedColumns", true)
        .withOption("fixedRows", true)
