Hello I have completed the table style export to OOXML just yesterday however the code needs a lot of ironing out. About exporting the tables to open document format. The tables created in excel are available in the xlsx zip at /tables/table#.xml where # is the number of the table defined in excel so if you define 4 tables., you will have 4 xml files in there one each. This data is parsed and successfully imported into calc. I spoke with markus some time ago about exporting table styles to open document. He mentioned writing a rfc or something later on for that so that is on hold. The export to excel of these db ranges will be done only for those db ranges that use any table formatting. This should not be that difficult, I realised that this only involves searching through the ScDBData collection and identifying the ranges that have formatting and writing the xml for them in /tables/.. Even if db ranges are stored as expressions or anything in calc, they will be easily exportable to excel. I think we will not have to worry about that. Once thats done full excel support for table styles will be achieved. I will push that soon.
