how do I create array with numbers and characters to then put into a table?

I'm trying to create a table from an array for which I need empty certain coluns to display blank (or NA). I tried this....

switch n        
        case 1
           sumT =array2table({k,ZIA,f1pk,'_','_','_',R2,Irms,Pload},'VariableNames',{'k',' ZIA', 'f1pk','fres1','fres2','f2pk','R2','Irms','Pload'})
        case 2
           sumT =array2table({k,ZIA,'_',f1,'_','_',R2,Irms,Pload},'VariableNames',{'k',' ZIA', 'f1pk','fres1','fres2','f2pk','R2','Irms','Pload'}) 
        case 3
           sumT =array2table([k,ZIA,'_','_',f2,'_',R2,Irms,Pload],'VariableNames',{'k',' ZIA', 'f1pk','fres1','fres2','f2pk','R2','Irms','Pload'})  
        case 4
            sumT =array2table([k,ZIA,'_','_','_',f2pk,R2,Irms,Pload],'VariableNames',{'k',' ZIA', 'f1pk','fres1','fres2','f2pk','R2','Irms','Pload'}) 
        otherwise
            disp('oops')
end

I've tried :

array2table({k,ZIA,f1pk,'_','_','_',R2,Irms,Pload}...
array2table([k,ZIA,f1pk,'_','_','_',R2,Irms,Pload]...
array2table([{k,ZIA,f1pk,'_','_','_',R2,Irms,Pload}]....

etc, but none of these combinations seem to work.

    sumT =array2table([k,ZIA,f1pk,' ',' ',' ',R2,Irms,Pload],'VariableNames',{'k',' ZIA', 'f1pk','fres1','fres2','f2pk','R2','Irms','Pload'})
    

results in :

this one,

    sumT =array2table([{k,ZIA,f1pk,' ',' ',' ',R2,Irms,Pload}],'VariableNames',{'k',' ZIA', 'f1pk','fres1','fres2','f2pk','R2','Irms','Pload'})

generates this output.

How do I display the contents of the "containers}?

how can I include doubles and blanks in the same array and then display them as such in a table?

Thank you.

k = 1;
ZIA = 2;
f1pk = 3;
fres1 = NaN;
fres2 = NaN;
f2pk = NaN;
R2 = 7;
Irms = 8; 
Pload = 9;

sumT = table(k, ZIA, f1pk, fres1, fres2, f2pk, R2, Irms, Pload)

sumT = 1x9 table
    k    ZIA    f1pk    fres1    fres2    f2pk    R2    Irms    Pload
    _    ___    ____    _____    _____    ____    __    ____    _____

    1     2      3       NaN      NaN     NaN     7      8        9  

sumT.R2

ans = 7

Ok, this will work...

Is there a way to do '_' instead?

thank you.

I think I can figure it out...I missed your links.....

Thank you.
