Is Tabulator downloadDataFormatter callback deprecated? - tabulator

Question

I have a set of data that I want to download to an XLSX sheet with some pre-formatting of the data. For this purpose I was intending to use the documented downloadDataFormatter callback (https://tabulator.info/docs/5.4/callbacks#download).
When the page is rendered the data is present and can be exported to the XLSX file but without the formatting that I need. In the console of the browser it displays the following warning "Invalid table constructor option:","downloadDataFormatter".
Has this callback been removed or deprecated?
//Sample Data
var tableData = [
{name:"Bob",age:47},
{name:"Steve",age:17},
{name:"Jim",age:23},
]
//Example Table
var table = new Tabulator("#table", {
downloadDataFormatter:function(data){
//data - active table data array
data.forEach(function(row){
row.age = row.age >= 18 ? "adult" : "child";
});
return data;
},
data:tableData, //load data into table
height:200, //enable the virtual DOM
columns:[
{title:"Name", field:"name", width:200},
{title:"Age", field:"age", width:200},
],
});
function downloadData(){
table.download("xlsx", "data.xlsx", {sheetName:"MyData"});
}
.tabulator{
background-color:#f3f3ff;
}
<div id="table"></div>
<button onClick="downloadData()">
Download
</button>
