C＃中如何产生一场比赛支架HTML表格 [英] c# How to generate a tournament bracket HTML table
问题描述
所以我一直坚持这个问题的3个星期了，我不能为我的生命数字出来。
想做什么IM是让使用表这种输出/演示。
so i have been stuck with this issue for 3 weeks now and i couldn't for the life of me figure it out. what im trying to do is to get this kind of output/presentation using tables.
的http：// www.esl-world.net/masters/season6/hanover/sc2/playoffs/rankings/
它是一个蹴鞠比赛进行定标系统。
，所以我的模型看起来像这样
it's a bracketing system for a kickball tournament. so my model looks like this
public class Match{
public int id {get;set;}
public int teamid1 {get;set;}
public int teamid2 {get;set;}
public int roundnumber {get;set;}
public int winner {get;set;}
}
所以，我现在正在做的是我遍历回合先说，也有轮，我会做到这一点。
so, what i'm doing now is i loop through the rounds first say, there are for rounds i would do this
for(int r = 1; r < bracketRounds; r++){
for(m = 1; m < roundMatches +1; m++){
matchGroup = "<tr><td>" + team1 + "</td></tr>"
+ "<tr><td>vs</td></tr>"
+ "<tr><td>" + team2 + "</td></tr>";
}
}
但那么这将只是生产1列表将显示所有的比赛。想知道是否有人能帮助/我指向正确的方向如何，我应该接近，这样我可以插入后续行到第一行右侧所以它会像有一个输出中支架。
but then this would just produce a 1 column table that will show all the matches. was wondering if anyone could help / point me to the right direction as to how i should approach this so that i can insert the subsequent rows to the right of the first row so it'll have a bracket like ouput.
谢谢！

下面是我的尝试。我已经测试的代码2，3，4回合比赛。在这里显示了2轮，3轮比赛的输出：
Here's my attempt. I have tested the code for 2, 3, and 4 Round Tournaments. The outputs for a 2-Round and 3-Round tournament are shown here:
我用同样的模式，您提供的定义匹配。我添加了一个锦标赛类来生成测试数据
I have used the same model that you provided to define a Match. I have added a Tournament class to generate test data.

}

我已经用动态静态方法 GenerateHTMLResultsTable 生成的原始HTML。这是使用仅完成<表> 无需任何< DIV> 块
I have generated the raw HTML dynamically using the static method GenerateHTMLResultsTable. This was done using only <table> without any need for <div> blocks.

更新
用于生成HTML表参数的说明
正如你所看到的， column_stagger_offset 是由每列上移对准他们，他们是应该的方式量。在 effective_row 本质上是其中特殊的表格单元格本来已经有过没有垂直移位。知道了 effective_row 和 position_in_match_span 帮助确定需要在particuar单元格中显示（空白，TEAM1，TEAM2，或VS）。
As you can see, the column_stagger_offset is the amount by which each column is shifted up to align them the way they are supposed to. The effective_row is essentially where the particular table cell would have been had there been no vertical shift. Knowing the effective_row and the position_in_match_span helps determine what needs to be shown in that particuar cell (blank, team1, team2, or vs.).
当你已经注意到了，我在列迭代，每次一行。这似乎是最自然的考虑到HTML表也构建的方式，即创建行，添加单元格......创建行，加CELS ...等等。
As you've noticed, I am iterating over the columns one row at a time. That seems most natural considering that HTML tables are also constructed that way, i.e. create row, add cells ... create row, add cels ... and so on.
