How to make table border colour transparent

Really hate the light gray borders. The contrast is so low that it's problematic for accessibility.

I can't believe no one thought of including such a basic option, let alone the time it takes to implement, now that 2 years have gone by..

Hi all,

It doesn't exactly fix the problem, but if you make the background of the block this color, #dddddd, it makes the lines disappear because it's the same gray as the lines.

Should be available as a basic feature. Any news on it? 

I can't believe this isn't an option. Any update? 

I'm needing this feature too. Posting here hoping Articulate would snap out of the slumber.

Three years.... Three years to let us modify the color of the borders of a table.  And it still isn't done.  Good people of Articulate, please hear our cry!  Give us this option, please!  Add Attachment

Please make it true :)

Would like to see this basic option as well.
