How to remove commas when rendering arrays in DataTable?

[AlxndrVgt]

I'm using DataTable to render some values. One of the column is an array:

const data = {
  columns: ['Foo'],
  rows: [
    [ [ 1, 2, 3 ] ],
    [ [ 4, 5, 6 ] ],
  ],
};

It seems that arrays are automatically rendered as a comma separated string in DataTables:

Is there a way to provide another separator, e.g. if I want to use | or a space like this:

If you are trying to show the data in one column as shown on the screenshot, you can either provide the data as a string with separator of your choice or write a function that would change it for you

const formatData = (data) => data.toString().replaceAll(",", " | ");

const basicData = {
  columns: ["Foo"],
  rows: [[formatData([1, 2, 3])], [[4, 5, 6]]],
};
