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.

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})
T = 1×6 table
Var1 Var2 Var3 Var4 Var5 Var6 _____ ____________ _______ ____________ _________ ______________________________________________________ {[1]} {2×1 double} {[1 2]} {3×1 double} {[1 2 3]} {[1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 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
