Is there a way that will show a web page in a browser with all the cell and table boundaries visible, even if they have been programmed via HTML or CSS to have no borders? This would help me to debug tables where something to do with nesting, or colspan or rowspan, or similar things have gone wrong.
I know I can go through all my tables and add visible borders to them, and then remove them all afterwards, but this is a lot of hassle, and is error-prone. It would be great to have an option in the borwser that I can set that forces all borders to be visible, preferably in a way that makes it clear which borders are actually visible because they will always be so, and which are visible only because of this option. Also it would be best if this option does not alter the layout of the table at all - e.g. the artificially-added borders should not take up any additional space - maybe they have to "steal" space from the element they are surrounding or something.
Is anyone aware of a way of doing this?
