Calibre keeps converting to mobi with the lines running off the screen.
any other tool or workaround?
I'm guessing your tables are running off the screen? In theory you could convert the settings from px to % for widths but that's too much for me to talk about.
You could select linearize tables under conversion - look & feel but it'll be ugly.
