First up, thanks to Anton for the suggestion to put tab-characters in
the string. (blush:) Is it you Gregg who says we tend to look for
the hard way to do things too often?
As to Jason's question, you use 'para to set the tabs to the positions
you want. (Just looked it up.) ie...
view layout [
text-list para [tabs: [20 40 110 150]] data [
["a" "^-b" "^-c" "^-d" "^-e"]
["1" "^-2" "^-3" "^-4" "^-5"]
]
]
As Gregg said, you'd need to measure the strings if you want to set
the tabs based on their lengths. See the recent "Proportional-spaced
fonts with accent marks" thread for a discussion on measuring the
pixel-length of strings.
