组件能跨列和跨行展示，这个例子里，我们就试试这个功能。

ZetCode PyQt5 tutorial
In this example, we create a more
complicated window layout using
the QGridLayout manager.

import sys
from PyQt5.QtWidgets import (QWidget, QLabel, QLineEdit,
QTextEdit, QGridLayout, QApplication)
class Example(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
title = QLabel('Title')
author = QLabel('Author')
review = QLabel('Review')
titleEdit = QLineEdit()
authorEdit = QLineEdit()
reviewEdit = QTextEdit()
grid = QGridLayout()
grid.setSpacing(10)
grid.addWidget(title, 1, 0)
grid.addWidget(titleEdit, 1, 1)
grid.addWidget(author, 2, 0)
grid.addWidget(authorEdit, 2, 1)
grid.addWidget(review, 3, 0)
grid.addWidget(reviewEdit, 3, 1, 5, 1)
self.setLayout(grid)
self.setGeometry(300, 300, 350, 300)
self.setWindowTitle('Review')
self.show()
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
我们创建了一个有三个标签的窗口。两个行编辑和一个文版编辑，这是用QGridLayout模块搞定的。
grid = QGridLayout()
grid.setSpacing(10)
创建标签之间的空间。
grid.addWidget(reviewEdit, 3, 1, 5, 1)
我们可以指定组件的跨行和跨列的大小。这里我们指定这个元素跨5行显示。
