You can get the second xAxis value from the right element in categories array:

        point: {
            events: {
                click: function() {
                    var tableDate = this.category,
                        secondValue = this.series.chart.xAxis[1].categories[this.x];

                    console.log(tableDate, secondValue);
                }
            }
        }
