How You Can Format a Multiline Header
If you want the title of a column to appear on multiple lines, use the OpenROAD system constant for a new line, HC_NEWLINE. For example, the following statement results in a two-line column title:
field(movie[*].director).title = 'Director''s' +
HC_NEWLINE + 'Name';
The result looks like this:
Director's
Name
