text wrap on table

Tables are awesome, however if I have a long line and it exceeds my terminals width, I'd like to be able to wrap based on cellwidth - i used cellwidth but it doesn't seem to have an impact on the table. Here's my code -

```go
err := termui.Init()
if err != nil {
panic(err)
}
defer termui.Close()
rows1 := [][]string{
[]string{"header1", "header2", "header3", "header4"},
[]string{"你好吗", "Go-lang is so cool", "Im working on Ruby a long sentance Im working on Ruby a long sentance Im working on Ruby a long sentance", "Im working on Ruby a long sentance Im working on Ruby a long sentance Im working on Ruby a long sentance"},
[]string{"2016", "10", "11", "11"},
}

table1 := termui.NewTable()
table1.Rows = rows1
table1.FgColor = termui.ColorWhite
table1.BgColor = termui.ColorDefault
table1.Y = 0
table1.X = 0
table1.Width = 59
table1.Height = 7
table1.Analysis()
table1.SetSize()
table1.CellWidth = []int{5,5,10, 5}
termui.Render(table1)

rows2 := [][]string{
[]string{"header1", "header2", "header3"},
[]string{"Foundations", "Go-lang is so cool", "Im working on Ruby"},
[]string{"2016", "11", "11"},
}

table2 := termui.NewTable()
table2.Rows = rows2
table2.FgColor = termui.ColorWhite
table2.BgColor = termui.ColorDefault
table2.TextAlign = termui.AlignLeft
table2.Separator = false
table2.Analysis()
table2.SetSize()
table2.BgColors[2] = termui.ColorRed
table2.Y = 10
table2.X = 0
table2.Border = true

termui.Render(table2)
termui.Handle("/sys/kbd/q", func(termui.Event) {
termui.StopLoop()
})
termui.Loop()
```

I want to be able to wrap for example 3rd (or 2nd if you prefer 0 indexing) to next row based on some parameter I desire it to be -- is there anything prebuilt like that?

Start with the table created by termui.NewTable and trace how Analysis, SetSize, and CellWidth affect rendering. Check the table implementation and existing tests, if present; done means long cell text wraps into subsequent rows according to the requested cell width without breaking other table layout.
