Tabulator: Update column definition after data is loaded - tabulator

Question

I am using autoColumns: true and data loaded through the builtin ajax call ajaxURL: "/...". After data is loaded I would like to dynamically update a few columns to allow dropdowns to be used. I know I could pre-define the column definitions prior to loading data but I am trying to do this dynamically.
In the code example below, I am adding new columns after data is loaded dynamically through a razor loop. This builds select lists dynamically and I used it as a POC to test part of what I need to do with updating column definitions.
How do I replace an existing columns definition and trigger an update without replacing the cells below data?
After the column definition is updated while keeping data how do I make sure the editor "select" is set to the cell value, my thinking this would happen automatically after the definition is updated.
Thanks!

var aColumns = table.getColumns();
for (var i = 0; i < aColumns.length; i++) {
if (aColumns[i]._column.field == 'Status') {
console.log(aColumns[i]._column.defitions);
aColumns[i]._column.definition.editor = "select";
var obj = {
key1: "value1",
key2: "value2"
};
var obj2 = {
values: obj
};
aColumns[i]._column.definition.editorParams = obj2;
}
}
}

table.setColumns is my friend. Before I could use this I needed to build the column definition from the returned column data. Seems like an opportunity for a new feature instead of a quick loop to do this directly. This answers both questions, first to update an existing definition and to not replace the existing data.
var newColumns = [];
var aColumns = table.getColumns();
for (var i = 0; i < aColumns.length; i++) {
if (aColumns[i]._column.field == 'Status') {
console.log(aColumns[i]._column.defitions);
aColumns[i]._column.definition.editor = "select";
var obj = {
key1: "value1",
key2: "value2"
};
var obj2 = {
values: obj
};
aColumns[i]._column.definition.editorParams = obj2;
}
newColumns.push(aColumns[i]._column.definition);
}
console.log(newColumns);
table.setColumns(newColumns);
