[bug] A long string causes the table to render extra rows

[27149chen]

code:

data := [][]string{
    {"1/1/2014", "Domain name", "2233", "$10.98"},
    {"1/1/2014", "January Hosting", "2233", "$54.95"},
    {"1/4/2014", "February Hosting a very very long message", "2233", "$51.00"},
    {"1/4/2014", "February Extra Bandwidth", "2233", "$30.00"},
}

table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Date", "Description", "CV2", "Amount"})
table.SetBorders(tablewriter.Border{Left: true, Top: false, Right: true, Bottom: false})
table.SetCenterSeparator("|")
table.SetAlignment(tablewriter.ALIGN_LEFT)
table.AppendBulk(data)
table.Render()

result:

DATE	DESCRIPTION	CV2	AMOUNT
1/1/2014	Domain name	2233	$10.98
