I am trying to vary the velocity relaxation factor between 0.2 and 0.5 .

Here is my code, what is wrong with it

relaxationFactors
{
    // Conservative settings to solve reliably on bad
    // meshes
    equations
    {
        UEqn               table ((0 0.2) (0 0.5));

        k               0.5;
        omega           0.5;
    }

    fields
    {
        p               0.3;
        U            table ((0 0.2) (0.5 0.5));
    }
}

I received the following error

	
	
--> FOAM FATAL IO ERROR: 
wrong token type - expected Scalar, found on line 116 the word 'table'

file: /home/openfoam/system/fvSolution/relaxationFactors/equations/U at line 116.

    From function Foam::Istream& Foam::operator>>(Foam::Istream&, Foam::doubleScalar&)
    in file lnInclude/Scalar.C at line 101.

FOAM exiting

The entire case works fine with no issue with an exact velocity relaxation factor such as state U 0.6;

But I would like to vary it between intervals.

Hello,

What OpenFOAM version are you using?

Version 11.0

AFAIK you cannot use time variable relaxation factors in the foundation branch (openfoam.org, OpenFOAM 11).
It is only possible in the OpenCFD branch (openfoam.com) since version v2112 (see release notes here)
