Creating a tournament bracket in HTML using a table structure

Question

Creating a tournament bracket in HTML using a table structure

For the past 3 weeks, I've been grappling with a problem that has me stumped. I just can't seem to figure it out for the life of me. What I'm attempting to achieve is a specific output or presentation using tables.

Here's an example of what I'm aiming for:

This setup resembles a bracketing system for a kickball tournament. Here's how my model looks:

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;}
}

Right now, I'm looping through the rounds. For instance, if there are four rounds, I would proceed as follows:

for(int r = 1; r < bracketRounds; r++){
    for(int m = 1; m < roundMatches +1; m++){
        matchGroup = "<tr><td>" + team1 + "</td></tr>"
                  + "<tr><td>vs</td></tr>"
                  + "<tr><td>" + team2 + "</td></tr>";
    }
}

The issue here is that this code snippet only generates a single column table displaying all the matches. I'm seeking guidance on how to modify this approach so that subsequent rows can be inserted next to the initial row, creating a bracket-like layout.

Any help or pointers in the right direction would be greatly appreciated. Thank you!

Answer №1

My analysis reveals the successful implementation and testing process for 2, 3, and 4 Round Tournaments. The outcomes of a 2-Round and 3-Round tournament can be viewed below:

The approach revolves around utilizing the provided model to define a Match. Additionally, a Tournament class is included for generating test data.

Match.cs - Model Definition

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace tournament
{
    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; }

        public Match(int id, int teamid1, int teamid2, int roundnumber, int winner)
        {
            this.id = id;
            this.teamid1 = teamid1;
            this.teamid2 = teamid2;
            this.roundnumber = roundnumber;
            this.winner = winner;
        }
    }

    public class Tournament
    {
        public SortedList<int, SortedList<int, Match>> TournamentRoundMatches { get; private set; }
        public Match ThirdPlaceMatch { get; private set; }

        public Tournament(int rounds)
        {
            this.TournamentRoundMatches = new SortedList<int, SortedList<int, Match>>();
            this.GenerateTournamentResults(rounds);
            if (rounds > 1)
            {
                this.GenerateThirdPlaceResult(rounds);
            }
        }

        // Additional methods and functionalities included here...
    }
}

To dynamically generate HTML output, the static method GenerateHTMLResultsTable was skillfully implemented. This HTML generation process solely relies on <table> structure without any dependency on <div> constructs.

Program.cs - HTML Generation Logic

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace tournament
{
    class Program
    {
        static string GenerateHTMLResultsTable(Tournament tournament)
        {
            // Method implementation details omitted for brevity...
        }

        // Main program logic for initializing test data and generating HTML results tables...
        
    }
}

Detailed Explanation of HTML Table Generation Parameters

In-depth examination of parameters like column_stagger_offset sheds light on the precise alignment adjustments made in each column. Understanding the concept of effective_row assists in determining the content display within particular table cells (empty space, team information, or 'VS' notation).

The iterative column-by-column approach mirrors the essence of constructing HTML tables, following a sequential row creation pattern along with cell additions per iteration.
