Matrix display - Unknown parameter '0' for row 0, column 0 error -- TN #4

hnhegde

Hello,
I am trying to display data in a matrix format using DataTables. I went through TN #4 and I believe I have covered all the aspects mentioned there in, especially the note pertaining to:

 # cells = # rows * # columns

However, I am still getting this error. Have uploaded my debug trace at: http://debug.datatables.net/osevaz
Would appreciate inputs from seasoned hands,

Regards,
Harsha

Hi Harsha,

I presume that the error is happening for the #returnsDueByStateTable table? The reason for that is that the data being returned from the server for each row is in the format:

    {
        "May 7, 2017": null,
        "July 31, 2017": null,
        "May 31, 2017": null,
        "county": "",
        "May 15, 2017": 1,
        "DT_RowId": "row_1"
    }

But you haven't told DataTables which property should be used for each column. You would need to have something like:

columns: [
  { data: "May 7, 2017", defaultContent: '' },
  ...
]

See this section of the manual for more details.
