How to display matrices in cell array in a table?

I have a cell array, and each element of the cell array is a matrix. But when I use cell2table to show the array, the table only shows that it is a 4*1 matrix instead of showing the actual value of the matrix. Is there a way to use cell2table to display the matrix values?
Here is my code, the cell array with matrix is named "x". Currently, I have to use celldisp, but it is not a presentable format.
clear
close all
clc
Q1 = [1 0 0 0; 0 1 0 0; 0 0 0 0; 0 0 0 1];
Q2 = [2 0 0 0; 0 0 0 0; 0 0 1 0; 0 0 0 1];
Q3 = [2 0 0 0; 0 0 0 0; 0 0 1 0; 0 0 0 2];
Q4 = [2 0 0 0; 0 0 0 0; 0 0 2 0; 0 0 0 2];
Q5 = [2 0 0 0; 0 0 0 0; 0 0 2 0; 0 0 0 1];
%{
[u,x] = longdyne(Q1);
cell2table(u,"VariableNames",["u0" "u1" "u2" "u3" "u4" "u5" "u6" "u7" "u8" "u9"])
%cell2table(x,"VariableNames",["x0" "x1" "x2" "x3" "x4" "x5" "x6" "x7" "x8" "x9" "x10"])

No, there is not. table() objects are not designed for display purposes. In every case in which an entry is multiple lines, table() will only display sizes and datatype.
T = table({1}, {(1:2).'}, {1:2}, {(1:3).'}, {1:3}, {1:20})
However, row vectors sometimes have their values displayed.

you can use array2table & cell2tmat together to display cell array content present in the table as shown below
clear
close all
clc
Q1 = [1 0 0 0; 0 1 0 0; 0 0 0 0; 0 0 0 1];
Q2 = [2 0 0 0; 0 0 0 0; 0 0 1 0; 0 0 0 1];
Q3 = [2 0 0 0; 0 0 0 0; 0 0 1 0; 0 0 0 2];
Q4 = [2 0 0 0; 0 0 0 0; 0 0 2 0; 0 0 0 2];
Q5 = [2 0 0 0; 0 0 0 0; 0 0 2 0; 0 0 0 1];
[u,x] = longdyne(Q1);
Q1x = array2table(cell2mat(u),"VariableNames",["u0" "u1" "u2" "u3" "u4" "u5" "u6" "u7" "u8" "u9"])
array2table(cell2mat(x),"VariableNames",["x0" "x1" "x2" "x3" "x4" "x5" "x6" "x7" "x8" "x9" "x10"])
[u,x] = longdyne(Q2);
Q2x = array2table(cell2mat(u),"VariableNames",["u0" "u1" "u2" "u3" "u4" "u5" "u6" "u7" "u8" "u9"])
array2table(cell2mat(x),"VariableNames",["x0" "x1" "x2" "x3" "x4" "x5" "x6" "x7" "x8" "x9" "x10"])
[u,x] = longdyne(Q3);
Q3x = array2table(cell2mat(u),"VariableNames",["u0" "u1" "u2" "u3" "u4" "u5" "u6" "u7" "u8" "u9"])
array2table(cell2mat(x),"VariableNames",["x0" "x1" "x2" "x3" "x4" "x5" "x6" "x7" "x8" "x9" "x10"])

array2table(cell2mat(x),"VariableNames",["x0" "x1" "x2" "x3" "x4" "x5" "x6" "x7" "x8" "x9" "x10"])
%}
function [u,x] = longdyne(QN)

F{1,10} = -1*((R+B.'*P{1,10}*B)^(-1))*B.'*P{1,10}*A;
for i = 9:-1:1
P{1,i}=A.'*P{1,i+1}*A-A.'*P{1,i+1}*B*((R+B.'*P{1,10}*B)^(-1))*B.'*P{1,10}*A+QN;
F{1,i} = -1*((R+B.'*P{1,i+1}*B)^(-1))*B.'*P{1,i+1}*A;
end
%celldisp(F)
for i = 1:10
u{1,i}=F{1,i}*x{1,i};
x{1,i+1}=A*x{1,i}+B*u{1,i};
end
end
hope this helps
