Show us the whole code.....and tell more clearly what you want.

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

Sir, tell me little bit clearly how and where can use these lines.

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
