After implementing the {style, text, attribute} for the cell, when I group on another column, the grouping row for this cell (the {text} of the render is a number) now shows NaN, rather than the sum. How can I get the sum to display, now that I'm implementing the render method for this column? This is how the column is defined:
{ title: ap, editable: canEdit, dataIndx: key, datatype: "float", format: nbrFormat, summary: { type: "sum" }, align: "right" }
return {
style: 'background-color:' + color,
text: 111,
attr: 'title="'+ hovertext + '"'
}
