Hi 
Giacomo Socini ,

If you want to add name and surname in one column, then please try following steps,  

1. create a block with expressions and add two Input parameter of Name and Surname and 

2 add them to 2 expression with space and 

3. add that block in column of table (in which you want to show the name and surname)

4.Now pass the table.list.current.entity.name and table.list.current.entity.surname

You will able to see the name and surname in single column.

Hope this helps,

Komal.

Hello,

this the solution that I use.

1. Create an Attribute composed by the two column (name and surname)
2. Use the attribute inside data grid column

Bye!
