EDITED TO REPRODUCE OIRIGINAL ISSUE FOR OTHERS THAT MIGHT RUN INTO THE SAME ISSUE

[... or the documentation is missing some relevant setup information]

When trying to convert a pipe-based markdown table to HTML, the result does not include any form of HTML table even with advanced extensions enabled. Instead, the result includes the input text in paragraph blocks and .

This can be reproduced with .netfiddle as follows and the latest version of Markdig (0.24.0):

using System;
using System.IO;
using Markdig;
using Markdig.Renderers;
using Markdig.Parsers;

public class Program
{
	private static string Render(string markdown)
	{
		var writer = new StringWriter();
		var renderer = new HtmlRenderer(writer);
		var pipeline = new MarkdownPipelineBuilder()
			.UseAdvancedExtensions()
			.UsePipeTables()
			.Build();
		var document = MarkdownParser.Parse(markdown, pipeline);
		// pipeline.Setup(renderer); <-- Was missing this. Uncomment to fix this issue
		renderer.Render(document);
		writer.Flush();
		return writer.ToString();
	}

	public static void Main()
	{
		var markdown = "a | b \r\n" + "-- | - \r\n" + "0 | 1 ";
		var html = Render(markdown);
		Console.WriteLine(html);
	}
}

And the output:

<p>a</p>
<p>b</p>
<p>0</p>
<p>1</p>
