Hello,
I have table variable (Input_table) like this
''1'' ''8'' ''2'' ''5'' '1' '1' ''Z'' ''F'' ''1'' ''3'' ''C'' ''5'' ''Y'' ''U'' ''4'' ''Q'' ''3''
''4'' ''4'' ''0'' ''9'' '1' '8' ''B'' ''R'' ''1'' ''2'' ''E'' ''8'' ''1'' ''Z'' ''1'' ''N'' ''X''
I want to convert every row into one string so the output to be array of 2 rows
'182511ZF13C5YU4Q3'
'440918BR12E81Z1NX'
I have tried
join(char(table2cell(Input_table))
but I get the error
Error using char
Cell elements must be character arrays.

Can you use valid matlab syntax to show how to create an example of your table, or attach your table as a mat file. Right now, it's very unclear how the data is stored in your table.
Perhaps, you should also explain how the table was created in the first place.

I imported the data from an excel sheet as categorical array. It was somewhat manual to work to create my table
Yes, you made a complete mess of it. And you would be better off asking a new question on how to import the data correctly in the first place, rather than attempting to fix the mess afterward.
All the table variables are indeed categorical. Some of the categories have the quote ' embedded in the category (that is the ' you see when looking at the table is not the ' that matlab typically surround char arrays with, it's actual part of the data), others do not.
The simplest way to fix the mess after the fact:
join(erase(string(Exampletable{:, :}), "'"), '', 2)
which:
- extracts the content of the table as a categorical array
- converts the categorical array into a string array
- erases the ' from the string array
- joins the string array across the column
But again, a better approach would be to import the data correctly in the first place, so ask a new question.

s={'1' '8' '2' '5' '1' '1' 'Z' 'F' '1' '3' 'C' '5' 'Y' 'U' '4' 'Q' '3'
'4' '4' '0' '9' '1' '8' 'B' 'R' '1' '2' 'E' '8' '1' 'Z' '1' 'N' 'X' }
a=cellstr(reshape([s{:}],size(s)))

s={'1' '8' '2' '5' '1' '1' 'Z' 'F' '1' '3' 'C' '5' 'Y' 'U' '4' 'Q' '3'
'4' '4' '0' '9' '1' '8' 'B' 'R' '1' '2' 'E' '8' '1' 'Z' '1' 'N' 'X' }
a=join(s,2)
You can add a delimiter
a=join(s,'',2)
