Remove column separators in tables

[ChausseBenjamin]

As shown in the table demo, there is a method to remove row separators:

ui.Render(primary)

table2 := widgets.NewTable()
table2.Rows = [][]string{
    []string{"header1", "header2", "header3"},
    []string{"Foundations", "Go-lang is so cool", "Im working on Ruby"},
    []string{"2016", "11", "11"},
}
table2.TextStyle = ui.NewStyle(ui.ColorWhite)
table2.TextAlignment = ui.AlignCenter
table2.RowSeparator = false
table2.SetRect(0, 10, 20, 20)

ui.Render(table2)

The table widget seems very promising to display things as a grid (for example I am attempting to make my own terminal based battleship). Only not having the option to hide column separators makes it impossible to do so...
