PyQt5基础学习-QTableWidget().findItems(根据文本找出所属位置) 1.QTableWidget().setItem(根据位置设置元素) 2.QTableWidget().verticalScrollBar().setSliderPosition(定位到某一行)

根据查找的文本，对表格中的元素进行搜索, 搜索到的结果返回为item元素, 通过item.row()返回行, item.col()返回列

"""
在表格中快速定位到特定的行

1. 数据的定位: findItems
2. 如果找到满足条件的单元格, 会定位到单元格所在的行: setSliderPosition(row)
