for j=1:1:14
for i=1:ne
Ecc=eval(['Ee',num2str(i)]);
acc=[0.3*acce(j,2);acce(j,2);0;Ecc.*(acce(j,2))';0.3*acce(j,2);acce(j,2);0;Ecc.*(acce(j,2))'];
mas = eval(['m',num2str(i)]); %% calling global elemental mass matrix
eval(['force',num2str(i),'=mas*acc']);
end
FG=[]; %%%%%-------ASSEMBLE FORCE VECTOR--------
FG=zeros(N,1);
m=5;
for n=1:1:ne %Calling elements
for i=1:1:8
d2=dof(n,m+i-1);%Calling degree of freedom for second node
force=eval(['force',num2str(n)]);%Calling elemental force vector
FG(d2,1)= FG(d2,1)+force(i,1);%calling element of the elemental force vector and adding to global force vector
end
end
end
here i want to save every time the FG(N by 1) in the name of FGf in a continuous column same table

You can add lines:
to arrays with index (end+1) --- multiple: (end+1 : end+length())
to tables with function height() +1
also cat(1, ...) or vertcat() should work on both and can be used for multiple lines or vectors

Its hard to understand your intention completely but maybe you can find a solution in this code.
You can operational add the force values to a zero vector with '+' or
add/concatenate the force vector to the zero vector
% dof function
function y = dof(a,b)
y = a+b;
function to_solve
% example variables
ne = 3;
Ee1 = 2;
Ee2 = 3;
Ee3 = 5;
m1 = 2;
m2 = 3;
m3 = 5;
acce = rand(4,2);
N = 3;
% code
for j = 1:1:4
for i = 1:ne
Ecc = eval(['Ee',num2str(i)]);
acc = [0.3*acce(j,2); acce(j,2); 0; Ecc.*(acce(j,2))'; 0.3*acce(j,2); acce(j,2); 0; Ecc.*(acce(j,2))'];
mas = eval(['m',num2str(i)]); %% calling global elemental mass matrix
eval(['force',num2str(i),'=mas*acc']);
end
FG = []; %%%%%-------ASSEMBLE FORCE VECTOR--------
% FG = zeros(N,1);
m = 5;
for n = 1:1:ne %Calling elements
for i = 1:1:8
d2 = dof(n,m+i-1); % Calling degree of freedom for second node
force = eval(['force', num2str(n)]); % Calling elemental force vector
%% == original ==
% FG(d2,1) = FG(d2,1) + force(i,1); % calling element of the elemental force vector and adding to global force vector
%% == add values at position d2 and trailing ==
if d2 > length(FG)
FG(end+1:d2,1) = 0;
end
FG(d2,1) = FG(d2,1) + force(i,1);
%% == add vector ==
% FG = vertcat(FG, force(i,1)); % calling element of the elemental force vector and adding to global force vector
end
end
end
