I’m assuming you are using the format command. Determine the maximum number of spaces for your first column and the maximum number of spaces for your second column ( the second number may not be necessary so long as you know you won’t go over the specified number of spaces per line). See the format example below:
set Pat_Header [format “%-41s %-24s” $Pat_Name $Pat_ID]
The “s” identifies it as a string and the “-” left justifies the column.
Hope this is what you were looking for.
