Memory leak

[xerenahmed]

There is an excessive memory usage problem

Codes

        var buf bytes.Buffer
	table := tablewriter.NewWriter(&buf)
	table.SetHeader([]string{"Head", "Head", "Head", "Head", "Head", "Head"})

	var maxDataCount uint16
	for _, tr := range tl.Times {
		length := uint16(len(tr))
		if length > maxDataCount {
			maxDataCount = length
		}
	}

	for i := uint16(0); i <= maxDataCount-1; i++ {
		var row []string
		for j := 0; j < len(tl.Times); j++ {
			tr := tl.Times[j]
			data := "-"
			if len(tr)-1 >= int(i) && tr[int(i)] != "" {
				data = tr[int(i)]
			}
			row = append(row, data)
		}

		table.Append(row)
	}

	table.Render()
	tl.TimesMarkdown = buf.String()
