表格技巧二则
Aug 20, 2004 Author: | Filed under: UncategorizedTable Layout
以前光知道 table-layout 用于解决表格 连续英文字符的撑开 问题。原来没这样还可以加速页面的渲染时间。
Table rendering performance can be increased by specifying the tableLayout property. This property causes Internet Explorer to incrementally render the table, providing users with information at a faster pace. Using the tableLayout property, the layout of a table is determined in the following order:
From information in the width property for the col or colGroup objects.
By analyzing the formatting of the first table row.
By an equal division of the columns.
First, information from the width property of the COL or COLGROUP object is used if it is available. If it is unavailable, then formatting for the first table row is taken into account. Lastly, if formatting is not available for the COL or COLGROUP objects, or the first table row, table layout is determined by an equal division of the columns.
Printing Tables on Multiple Pages
这个倒是早就知道了。控制很长的表格打印时候的处理办法。
When a page containing a table is printed, the CSS attributes page-break-before and page-break-after can be used to specify where in a table the break should occur. This is helpful for Web sites that implement large tables to organize pages. In addition, the display property exposes the table-header-group and table-footer-group possible values, which specify that the tHead or tFoot objects are always before or after any table rows. Using these possible values for the tHead and tFoot objects specifies that the header and footer will print on every page that a particular table spans.

一个关于正则表达式和Unicode的问题
Aug 20, 2004 Author: | Filed under: Uncategorized问题是这样的：
我希望表达式e中可以出现除’#'外的任何字符（包括任何unicode字符）
‘#’的unicode为u0023
一开始我想直接用[^#]+或[^u0023]+这样的，
结果发现这里的“全集“似乎不包含unicode字符，所以中国字也属于不匹配的
问题1: 当使用^运算符时，相对的”全集”是什么？
后来我决定使用[u0000-u0022]|[u0024-uFFFF]+
也就是说手动指定全集，把u0023空过去
结果发现竟然出现了语法错误~~~
错误提示是：
unclose literal string 未闭合的串字面值
而如果将原式改为
[u0000-u0023]|[u0024-uFFFF]+
或
[u0000-u0021]|[u0024-uFFFF]+
都不会有问题
最后，终于发现
在java中
System.out.println(”u0022″);竟然都有语法错误！
换句话说，问题出在u0022这个unicode值上
问题2:为什么只有u0022不行呢？
难道是bug?
后来，jinni自己给出了答案
在flash 输出 trace(u0022)，原来是 “
