I have a Unix Shell script which produces a plain text report. Horizontal alignment is achieved by inserting spaces so that the output appears to be in columns in the terminal.
Caption Caption Caption -------- -------- -------- Line 1 value 1 value 2 Line 2 value b bla bla Line 3 value 1 value 2 Line 4 value b bla bla
The report is automated to run regularly and a copy is sent via email. To make the formatting look right in a mail client I set the content-type to HTML and added
<PRE> pre-formatting tags around the entire message content.
This works well enough. However I would like to highlight certain lines, eg by changing the font to set the text and background color. How could I best do that?
I can replace the
</PRE> with a span to set a Mono-width font but how do I retain the blank spaces to keep the column/table appearance?
I tried to use actual HTML tables but this only works in some mail clients, in others the same message is illegible because most of the text becomes strung out in a very narrow (1 to 3 characters wide) very tall column. Also setting formatting options on table attributes behave wildly different between the few email clients that I have available for my own testing!
