根据标题字符串和所选行获取单元格值

如果这样做，您将得到：“分配前已引用局部变量’matchcol’”

要解决此问题，您应该在if循环中返回单元格：

#===================================================================# given a tablewidget which has a selected row...# return the column value in the same row which corresponds to a given column name# fyi: columnname is case sensitive#===================================================================def getsamerowcell(widget,columnname):    row = widget.currentItem().row()    #col = widget.currentItem().column()    #loop through headers and find column number for given column name    headercount = widget.columnCount()    for x in range(0,headercount,1):        headertext = widget.horizontalHeaderItem(x).text()        if columnname == headertext: cell = widget.item(row, x).text()   # get cell at row, col return cell
