Table for for loop

I am trying to add a table but it is only giving me the last iteration of the for loop. I am not sure how to do so, please help. Thanks!

Here is my code:

clc,clear
for E=0.1:0.1:0.9
syms tn1 tn2
 phi=atan(sqrt(1-E.^2)/E)+pi();
 fn=@(tn1) [0.1+exp(-E*tn1)./sqrt(1-E.^2).*sin(tn1.*sqrt(1-E.^2)+phi)]; %f0.9
 tn1=fzero(fn,2);
 fo=@(tn2) [0.9+exp(-E*tn2)./sqrt(1-E.^2).*sin(tn2.*sqrt(1-E.^2)+phi)]; %f0.1
 tn2=fzero(fo,2);
ftotal=tn1-tn2
end
table(E(:),ftotal(:))

E_vals=0.1:0.1:0.9;
num_E = length(E_vals);
for E_idx = 1 : num_E
 E = E_vals(E_idx);
 syms tn1 tn2
 phi=atan(sqrt(1-E.^2)/E)+pi();
 fn=@(tn1) [0.1+exp(-E*tn1)./sqrt(1-E.^2).*sin(tn1.*sqrt(1-E.^2)+phi)]; %f0.9
 tn1=fzero(fn,2);
 fo=@(tn2) [0.9+exp(-E*tn2)./sqrt(1-E.^2).*sin(tn2.*sqrt(1-E.^2)+phi)]; %f0.1
 tn2=fzero(fo,2);
 ftotal(E_idx) = tn1-tn2;
end
table(E_vals(:), ftotal(:))
