	Files       int      `json:"files" tableify:"-,5"`
	LastUpdated string   `json:"lastUpdated" tableify:"Updated"`
}

func main() {
	repolist := []Repo{
		{
			Name:         "yum-repo",
			Files:        45,
			LastUpdated:  "2018-01-06T07:45:22Z",
		},

			LastUpdated:  "2018-01-06T08:05:09Z",
		},
	}

	t := tableify.New()
	t.SetHeadersFromStruct(new(Repo))
	t.AddRowObjectList(repolist)
	t.Print()
}

  • name or -

    eg: tableify:"-", tableify:"NAME"

  • name,width

    eg: tableify:"-,20"
