Thanks for the reply, but I’m sorry to say the solution is not really helping…It is impossible to tell clients about cutting columns to avoid the issue, and a smaller screen should not be an issue.
We found the issue is the Cost and Profit <td> are existing without responsive width, while other columns are with responsive width such as {integer}%. When we hard coded a percentage width on Cost and Profit column just through the F12 console, the problem has been solved. Please suggest on any simple fixes on adding the width style on the extra 2 columns?
