What, exactly, are the symbols (and tables) you're trying to reproduce?

(Show us images of the PDF pages.)

A "shaded table" with transparent PNG? That just sounds like it's asking for trouble once users fiddle with their settings.

(I hate websites that do that with my color overrides.)

(Also, images-of-tables... poor idea. Better to do actual HTML tables. See my detailed topics below.)

Yes, that is also a possibility.

Amazon/Kindles have had oddities with transparency for years.

See my famous:

where I tested out various types of transparency.

And like Hitch said, Kindlegen always converted PNG + changed to white background too.

Calibre to MOBI/KF8 was able to somehow generate them fine... but Kindlegen (and Amazon's official ingestion system), nope.

Just gonna have to drop the alternate shading and face the customer.
I'm going to channel my inner-JSWolf here...

Zebra Striping (coloring alternate rows) is garbage.

Do not use it, do not promote it, do not continue spreading those abominations.

See the fantastic GIF: "How to make your tables less terrible".

Also see my posts in:

and my recent post yesterday in:

If you want even more examples, see my recent comments in:

So many people create "table-like graphics" + think it "looks nice", but in actuality, they're doing a complete disservice to their underlying data.
