I'm wondering whether you can make turn a progress bar into a stacked horizontal bar chart in tabulator?
There is no built in formatter with this functionality, but it is really simple to add your own Custom Formatter to add any type of formatting that you like:
{title:"Name", field:"name", formatter:function(cell, formatterParams, onRendered){
//cell - the cell component
//formatterParams - parameters set for the column
//onRendered - function to call when the formatter has been rendered
return "Mr" + cell.getValue(); //return the contents of the cell;
}}
