How to find the difference of values ​​in a row?

slate

( "columns": [
{ "data": "start_date" },
{ "data": "end_date" },
{ defaultContent: "?" },
])

I'm getting a table from the server side

and I want to find the difference in the value of the row and display it in the 3rd column.

How do I express the difference in dates in rows 1 and 2

You would get the values with cell().data(), and then use Moment.js to do the calculations - it's excellent for all time/date based operations.
