为什么QTableWidget的setItem得到的结果不对？我觉得应该是会按dos窗口显示的数据分别填到表格中的啊。哪里出了问题？

PySide.QtGui.QTableWidget.setItem(row, column, item)
Parameters:       
row – PySide.QtCore.int
column – PySide.QtCore.int
item – PySide.QtGui.QTableWidgetItem
Sets the item for the given row and column to item .

The table takes ownership of the item.

Note that if sorting is enabled (see PySide.QtGui.QTableView.sortingEnabled() ) and column is the current sort column, the row will be moved to the sorted position determined by item .

If you want to set several items of a particular row (say, by calling PySide.QtGui.QTableWidget.setItem() in a loop), you may want to turn off sorting before doing so, and turn it back on afterwards; this will allow you to use the same row argument for all items in the same row (i.e. PySide.QtGui.QTableWidget.setItem() will not move the row).

class PySide.QtGui.QTableWidget([parent=None])
class PySide.QtGui.QTableWidget(rows, columns[, parent=None])

看文档貌似可以在创建表格对象时就提供行列参数的，但是实际却不能这样使用，奇怪。
