table: defaults for row/header/footer align/valign; fixes #340

[jedib0t]

Proposed Changes

• the default align/valign option for every row (header+footer) is text.AlignDefault and text.VAlignDefault
• expose these as customizable options in table.Style().Format

To change the defaults, you'd do something like this:

		tw := table.NewWriter()
		tw.AppendHeader(table.Row{"#", "First\nName", "Last\nName", "Final\nState", "Misc.\nMulti-line\nNotes"})
		tw.AppendRows([]table.Row{
			{1, "Arya", "Stark", ":) 8)"},
			{20, "Jon", "Snow", ":( :( :(", "You know nothing, Jon Snow!"},
			{300, "Tyrion", "Lannister", ":)"},
		})
		tw.AppendFooter(table.Row{"#", "First\nName", "Last\nName", "Final\nState", "Misc.\nMulti-line\nNotes"})
		tw.SetStyle(table.StyleLight)
		tw.Style().Format.HeaderAlign = text.AlignCenter
		tw.Style().Format.HeaderVAlign = text.VAlignBottom
		tw.Style().Format.FooterAlign = text.AlignRight
		tw.Style().Format.FooterVAlign = text.VAlignTop
		fmt.Println(tw.Render())

to get:

Remember that column-configs takes precedence and will override the above.
