Redirecting conversation regarding GSoC Project to Mailing List

Hi Sarrah,

Replying from the UX/design POV, so maybe not really answering your questions.

The table style (TS) feature is supposed to supersede the AutoFormat dialog. TS 
are not only relevant on Calc but also (and probably more aware to users) in 
Writer. And access from the Stylist at the sidebar is possible there though it 
lacks a preview like in Draw/Impress. And the UI is missing to edit the TS. But 
the top PITA is this binary format.

* bug 49437: Writer/Calc: Use XML for serializing table autoformats instead of 
the current brittle binary format
* bug 105933: Means to modify existing table styles in a dialog
* bug 101802: Consolidate Writer and Draw/Impress sidebar table design content panel

The META ticket lists a gazillion internal issues that are also highly relevant

Previous GSoC project is documented at

UI proposal by the design team at

Hope that helps,
