CSS的“display: table-column”应该如何工作？
鉴于以下HTML和CSS，我在浏览器中看不到任何内容（在撰写本文时，Chrome和IE最新版本）。一切都崩溃到0x0像素。为什么？
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
section { display: table; height: 100%; background-color: grey; }
#colLeft { display: table-column; height: 100%; background-color: green; }
#colRight { display: table-column; height: 100%; background-color: red; }
#row1 { display: table-row; height: 100%; }
#row2 { display: table-row; height: 100%; }
#row3 { display: table-row; height: 100%; }
#cell1 { display: table-cell; height: 100%; }
#cell2 { display: table-cell; height: 100%; }
#cell3 { display: table-cell; height: 100%; }
</style>
</head>
<body>
<section>
<div id="colLeft">
<div id="row1">
<div id="cell1">
AAA
</div>

<div id="row2">
<div id="cell2">

可以试试这个：
>>> import array
>>> array
<module 'array' (built-in)>
>>> class A(array.array):
def __init__(self, *args):
super(array.array, self).__init__(*args)
print "init is fine for objects implemented in C"
>>> a=A('c')
init is fine for objects implemented in C
>>> 将看到相同的行为子类int、str等。
>>> import datetime
>>> class D(datetime.date):
def __new__(cls, year):
return datetime.date.__new__(cls, year, 1, 1)
>>> D(2008)
D(2008, 1, 1)和开发者交流更多问题细节吧，去 写回答
