Header or Grouping Above Column Name

[hitomebore]

Hi, I was wondering if metabase have an option in table visualization to group different columns and make header above those columns manually for the selected columns

So if I have table with 9 columns like below:

I would like to make 3 header above those 9 columns and it should look like this:

So multiple columns will have 1 extra header above them just for readability due to very wide table

Thanks for the help
