Formatting date for Tabulator cell to dd/mm/yy - tabulator

Question

I am using Tabulator for an external JSON source.
The source gives the DOB in this format: 2020-04-16T00:00:00.000+0000
which I want to convert to dd/mm/yy
I have included the moment library.
I am using this code:
{title:"Date of Birth", field:"birthDate", sorter:"date", width:200, sorterParams:{format:"DD/MM/YY"}},
But no change is displayed - i just get the original format.
I have also tried this, but it also did not work.
{title:"Date of Birth", field:"birthDate", sorter:"date", width:200, formatter:dateFormatter},
//custom date formatter
var dateFormatter = function(cell, formatterParams){
var value = cell.getValue();
if(value){
value = moment(value , "YYYY/MM/DD").format("MM/DD/YYYY");
}
return value;
}
Thanks for your suggestions.

Answer 1

You need the datetime formatter:
http://tabulator.info/docs/4.7/format#format-builtin
For your custom formatter you are missing the onRendered argument.

Answer 2

The following 2 formats landed up working for me. Kudos to #adrian-klaver for the pointer to option #2
Option 1:
{title:"Date of Birth", field:"dob", width:150, formatter:function(cell, formatterParams, onRendered){
var value = cell.getValue();
value = moment(value).format("DD/MM/YYYY");
return value;
}},
Option 2:
{title:"Date of Birth", field:"dob", width:150, formatter:"datetime", formatterParams:{
inputFormat:"YYYY-MM-DD HH:ii",
outputFormat:"DD/MM/YY",
invalidPlaceholder:"(invalid date)",
timezone:"America/Los_Angeles",
}
},
