I just updated my Matlab to 2020b.
I created a table:
tt = table({1;2;3;4;5},{'A';'B';'C';'D';[]},{9;10;11;12;[]},{'E';'F';'G';'H';[]})
tt = 5×4 table
Var1 Var2 Var3 Var4 _____ ____________ ____________ ____________ {[1]} {'A' } {[ 9]} {'E' } {[2]} {'B' } {[ 10]} {'F' } {[3]} {'C' } {[ 11]} {'G' } {[4]} {'D' } {[ 12]} {'H' } {[5]} {0×0 double} {0×0 double} {0×0 double}
In the previous matlab 2018 and lower, it is shown without { }, just the content of the cell. Is it possible to "display" it as before, without the { }?

If you really want to, you can. The formattedDisplayText function was introduced in R2021a.
I read about this one in a Community Highlight blog post.
tt = table({1;2;3;4;5},{'A';'B';'C';'D';''},{9;10;11;12;nan},{'E';'F';'G';'H';''});
str=formattedDisplayText(tt);
strrep(strrep(str,'{',' '),'}',' ')
ans =
" Var1 Var2 Var3 Var4 _____ __________ _______ __________ [1] 'A' [ 9] 'E' [2] 'B' [ 10] 'F' [3] 'C' [ 11] 'G' [4] 'D' [ 12] 'H' [5] 0×0 char [NaN] 0×0 char "

No, it is not.
However, if you only need that for display purposes, then
tt = table({1;2;3;4;5},{'A';'B';'C';'D';''},{9;10;11;12;nan},{'E';'F';'G';'H';''});
TT = varfun(@(V)categorical(string(V)), tt)
TT = 5×4 table
Fun_Var1 Fun_Var2 Fun_Var3 Fun_Var4 ________ ___________ ___________ ___________ 1 A 9 E 2 B 10 F 3 C 11 G 4 D 12 H 5 <undefined> <undefined> <undefined>
Notice I had to change the [] to ' ' or nan

Thanks. This workaround seems good.
Small "problem" is I have table with some column number, and some string. So I need to replace all the [] either with '' or NaN depend on the column class (manually). Any suggestion to do it automatically?
