hello!
I'm using in my program quite big qtable view. It has up to 400 columns and probably up to 1000 rows. In every row i need to make a lot of row spans (more or less 1 span for each 3 columns). Unfortunatelly scrolling this table is so slow, that program is unusable. Even small tables with spans are too slow to use. I'm using my own model subclassed from QAbstractItemModel. Problem still exists even if both data() and headerData() in the model returns empty QVariant. Are spans in qt that badly written, or am i doing sth wrong?
