Add support for html tables

[carbonrobot]

Initial thoughts on fluid interface

var table = new Table()
   .AddHeader(
        new HeaderRow(
            new HeaderCol().Text("Col 1"),
            new HeaderCol().Text("Col 2")
        ),
    )
   .AddBody();

<table>
    <thead>
        <tr><th></th><th></th></tr>
    </thead>
    <tbody>
        <tr><td></td><td></td></tr>
    </tbody>
</table>

Simple tables should be easier to implement

var table = new Table()
    .AddRow("Data in col A1", "Data in col A2", "Data in col A3")
    .AddRow("Data in col B1", "Data in col B2", "Data in col B3");

Rows should take IEnumerable<string>

var list = new List<string>();
list.AddRange(new string[] {"Data in col 1", "Data in col 2", "Data in col3"});

var table = new Table()
    .AddRow(list);
