Label Columns and Rows of Dat file

Hello Guys,,

How to I Label the rows of a dat file. to look like in the picture below

clear
clc
 
nu= 50;
ps=1;
 load(['CPU_nu_',int2str(nu),'_', int2str( ps),'.mat'],'E_NeNMF_R', 'M_NeNMF_R',...
     'E_NeNMF_V','M_NeNMF_V','E_AS_V','M_AS_V','E_AS_R','M_AS_R');
    
 
    figure_Col(1,2) = E_NeNMF_R;
    figure_Col(1,3) = M_NeNMF_R;
 
    figure_Col(2,2) = E_NeNMF_V;
    figure_Col(2,3) = M_NeNMF_V;
   
    figure_Col(3,2) = E_AS_R;
    figure_Col(3,3) = M_AS_R;
 
    figure_Col(4,2) = E_AS_V;
    figure_Col(4,3) = M_AS_V;
 
hdrs = {'Algorithm','E-step','M-step' 
    };

namedatfile= [int2str(nu) '_nu_' int2str(ps) '_pass.dat'];
fname = namedatfile;
txt=sprintf('%s\t',hdrs{:});
txt(end)='';
dlmwrite(fname,txt,'');
dlmwrite(fname,figure_Col,'-append','delimiter','\t');

But my table looks like this

How do i replace the '0's with names like in the first picture.
