Highcharts tooltip formatter function does not display values in table correct - if-statement

Question

I have created an if else statement in my highcharts tooltip formatter function in order to display y values from different point.series.name.
Values from first and second series in the array displays correct, but styling for the last series.name values (HINDCAST - SPREAD) does not display correct, because font-size and point.series.color does not show. I suppose the problem is the table tags? Please see fiddle

tooltip: {
shared: true,
useHTML: true,
formatter: function() {
var aYearFromNow = new Date(this.x);
aYearFromNow.setFullYear(aYearFromNow.getFullYear() + 5);
var tooltip = '<table><span style="font-size: 16px">' +
Highcharts.dateFormat('%e/%b/%Y', new Date(this.x)) + '-' + Highcharts.dateFormat('%e/%b/%Y', aYearFromNow) + '</span><br/><tbody>';
//loop each point in this.points
$.each(this.points, function(i, point) {
if (point.series.name === 'Observations') {
tooltip += '<tr><th style="font-size: 14px; color: ' + point.series.color + '">' + point.series.name + ': </th>' +
'<td style="font-size: 14px">' + point.y + '℃' + '</td></tr>'
} else if (point.series.name === 'BOXPLOT') {
const x = this.x;
const currentData = this.series.data.find(data => data.x === x);
const boxplotValues = currentData ? currentData.options : {};
tooltip += `<span style="font-size: 14px; color: #aaeeee">
Max: ${boxplotValues.high.toFixed(2)}<br>
Q3: ${boxplotValues.q3.toFixed(2)}<br>
Median: ${boxplotValues.median.toFixed(2)}<br>
Q1: ${boxplotValues.q1.toFixed(2)}<br>
Low: ${boxplotValues.low.toFixed(2)}<br></span>`;
} else {
tooltip += '<tr><th style="font-size: 14px; color: ' + point.series.color + '">' + point.series.name + ': </th>' +
'<td style="font-size: 14px">' + point.point.low + '℃ -' + point.point.high + '℃' + '</td></tr>' +
'</tbody></table>';
}
});
return tooltip;
}
},

Answer 1

You're closing the tbody before the last value (HINDCAST - SPREAD), once put outside the for loop it works :
...
tooltip += '<tr><th style="font-size: 14px; color: ' + point.series.color + '">' + point.series.name + ': </th>' +
'<td style="font-size: 14px">' + point.point.low + '℃ -' + point.point.high + '℃' + '</td></tr>'
}
});
tooltip += '</tbody></table>';
return tooltip;
...
