Hi, great project!

I use markdig in a project to normalize incoming Markdown files and to gather metadata about the document. Now some of these documents include tables and I noticed that they are not rendered at all (I use a JS renderer for markdown, but that one works just fine). As it turns out, markdig seems to strip all table symbols in the normalization step.

I have a reproduction, which closely resembles the actual code used: https://github.com/ricardoboss/markdig-table-normalization

The gist of it is this:

Program.cs

var markdownPipeline = new MarkdownPipelineBuilder()
    .UsePipeTables()
    .Build();

var content = File.ReadAllText("test.md");
var document = Markdown.Parse(content, markdownPipeline);
var builder = new StringBuilder();
var writer = new StringWriter(builder);
var renderer = new NormalizeRenderer(writer);
renderer.Render(document);

Console.Write(builder.ToString());

test.md

| Col | Col 2 | Col 3 |
|:----|:-----:|------:|
| left | center | right |
| spaaaaaaaaacer | spaaaaaaaaacer | spaaaaaaaaacer |

And I expected the output to be same or somewhat formatted, but the actual output is this:
