You can show a tooltip as a table using the template property in tooltipSettings.
The following steps describe how to show the table tooltip.
Step 1:
Initialize the tooltip template div as shown in the following html page.
<script id="tooltipTemplate" type="text/x-template">
<div id='templateWrap'>
<table style="width:100%; border: 1px solid black;">
<tr><td bgcolor="#00FFFF">${xValue}:</td><td bgcolor="#00FFFF">${yValue}</td><td bgcolor="#00FFFF">${value}</td></tr>
</table>
</div>
</script>Step 2:
Set the element id to the template property in tooltipSettings to show the tooltip template.
