True minimal table style

[ericnewton76]

I'm replacing hand written table output, which looked like this:

[2  [10         [12           [30                             [10         <-- these are just widths for ref
##  Column2     Col3          Col4                            Col5
--  ----------  ------------  ------------------------------  ----------
 1  data123                                                   col5 111
 2  data345                   col4data,row2                   col5 222

the curent hand code writes all the fields use Substring and Padright to keep alignments and truncate overflows and such.

And Minimal style is similar but not "as minimal" as this one... how difficult would it be to submit a PR and have basically TrueMinimal style ? I looked through TableContextRenderer and it seems to insist on either borders (everywhere) or no borders (anywhere) which realistically this is "Header bottom border only" which IMO is the "true minimal"...

public static Table TrueMinimal(this Table table) {
table.Border = TableBorder.None;
table.HeaderBottomBorder = "-" or "=";
table.ShowRowSeparator = false;
return table;
}

my workaround for now is

var table = new Table();
table.AddColumn("#", c => c.Width = 2);
table.AddColumn("Column2", c => { c.Width = 10; });
table.AddColumn("Col3", c => c.Width = 12);
table.AddColumn("Col4", c => { c.Width = 30; c.NoWrap = true; });
table.AddColumn("Col5", c => c.Width = 10);

//add a bogus row to simulate old render
table.AddRow(table.Columns.Select(c => new String('-', c.Width.GetValueOrDefault(0))).ToArray());

//adding rows

AnsiConsole.Write(table.NoBorder());

which requires every column to have a width specified
