QtitanDataGrid是一款適用于Qt的商業(yè)化DataGrid 組件，它使得表格數(shù)據(jù)可以直接面向終端用戶。這個組件吸收了用戶界面結(jié)構(gòu)顯示表格方面所有的現(xiàn)代化技術的精華，是目前Qt市場上唯一一款擁有如此高級功能和出色性能的網(wǎng)格組件。這個Qt數(shù)據(jù)網(wǎng)格組件使用純C++創(chuàng)建，運行速度極快，處理大數(shù)據(jù)和超大數(shù)據(jù)集的效果突出。QtitanDataGrid完全集成了QtDesigner，因而極易適應其他相似的開發(fā)環(huán)境，保證100%兼容Qt GUI。
