Hello Jam,
You can create a custom column with the formula similar to one shown below:
(‘Name:’||employee_details.employee_name||’<br>’||’City:’||employee_details.address||’<br>’||’Type: ’||travel_details.travel_type)
Note: Modify the column names and text as per requirement. The syntax differs from database to database and will need to be modified accordingly.
Here, the 
 tag is used to go to the next line. Basically the table understands the HTML tags which we are using. The output of the above code would be as below:

Thank You,
