代码异常地ugly, 所有直线都是用border property画出来的，里面嵌套了无穷多的table。
有什么好建议吗？Decision tree是动态生成的。 |

table。
No need to use tables. You could use absolute positions in CSS to achieve
the same effects.
Also there are javascript libraries for drawing charts.

发帖数: 14569 | 11 Absolute position won't work here because it is part of a dynamic page. It
is impossible to calculate how much draw space I have.
I first tried to use div + css border. To be frank, floated div is nightmare
, even with a CSS missing manual by hand, it is too tall a task for me.

发帖数: 14569 | 16 What is blend? can you give a link?
Do you mean Microsoft Expression Blend 3? I seriously doubt it, hook it up with any XML defined tree from database, allow user to edit it in web and save it back to database? I can't imagine any tool can easily handle it without much coding.
My experience with any software/package is:
More powerful software
=> Less Code & Beautiful result for task suppose to do
=> Much much harder to customize for your need
when it push to some degree, it is simply mission imp

How is it impossible? You can find out the size of current client area and
go from there.
nightmare
No, don't use float divs. Use one div as the container, then absolutely
position little div containers within. You could use javascript to
dynamically set the dimensions and positions.
Trust me, I did something like this before.

整个page由几块JSP构成，每块JSP都有可能有javascript动态生成的东西。我确实可以
从HTML DOM算确切位置，但是很麻烦。
Absolute position我记得是相对整个page的吧，那你每个div都挨个儿算(top, left)
和size?

It's relative to the first containing block with a non-static position
specification. IOW, you could conceptually do:
And the blocks above would be positioned within the container's
own coordinate system.
