Q: Change border style

Hello

Is there anyway to change the default border style for a table on 'Numbers for Mac' so I can alter the borders on Numbers for iOS without it going a different colour?

Currently when i try and deal with borders on my iPad it turns them blue with no way to change them black. I can however change to default style. If I can change the default style on my Mac then maybe this would work on my iPad.

Cheers

Rob
