Hi,
I have a table of 5 columns with strings, I would like to concatenate the two columns by a "_" and make them into one column.
Table A:
var1 var2 var3 var4 var5 ABC 123 aaa bbb ccc EFG 345 ddd eee fff into B: var1 ABC_123 EFG_345
How to do that?
Thanks.
Jennifer

In addition, in the var2, there are some string like 'N/A'. I want to replace 'N/A' by just nothing ''.
Thanks for any help.

Actually I did it with t.Var1 = strcat(t.Var1, '_', t.Var2)

Hi,
It is not possible to concatenate two columns after the table has been constructed. You can concatenate the two columns prior to constructing the table using the 'strcat' function.

Eh,
It's not true. I tried JFz's idea for tables already been constructed. It works! At least in Matlab 2016a or later versions.
