    could you point me to the answer ?

    Thank you

    Sorry, the thread din't help.

    Are you interested in only displaying the first element of srsRequirementDetails for each row?

    If so you can do something like this:

      columns: [
      {data: 'id'},
      {data: 'srsModuleName'},
      {data: 'srsRequirementDetails.0.categoryName'},
      {data: 'srsRequirementDetails.0.priorityName'},
      {data: 'srsRequirementDetails.0.statusName'},
      {data: 'srsRequirementDetails.0.requirement'},
      {data: 'srsRequirementDetails.0.reference'},
    
    ]

    I already tried this, but this only display first array element, or more specific indexed array element.
    But I want to display (Iterate) all nested array elements.

  • kthorngrenkthorngren Posts: 2,682Questions: 19Answers: 596

    As far as I know there is no provision to iterate an object and create new rows, using the above example. Each row is expected to be in its own array element. Can your server script return the data this way? You could then use Row Grouping to group the "modules".

    However you should be able to display array elements in one row using columns.render or you can use the Detailed Rows functionality if you want to hide/show the details.

    How do you want the details displayed, ie, one table row for all details or individual table rows for each detail?

    @Kevin I want to Display one table row for all details, but this what I'm not able to achieve using columns.render , Detailed Rows is not my case.

    If not possible then I will change My server side script data return policy and then Use Row Grouping to group the "modules".

    Thank you.

    Answer ✓

    Here is a simple example of looping through a nested array of objects to build an output string using columns.render:

    Hope you can adapt it to your data and output requirements.

    this is what I wanted to do. oops now again going to change script.
    thanks Kevin sir.

    but what about to display rest fields on separate column

    columns: [
      {data: 'id'},
      {data: 'srsModuleName'},
      {data: 'srsRequirementDetails.0.categoryName'},
      {data: 'srsRequirementDetails.0.priorityName'},
      {data: 'srsRequirementDetails.0.statusName'},
      {data: 'srsRequirementDetails.0.requirement'},
      {data: 'srsRequirementDetails.0.reference'},
     
    ]

    I'm afraid I don't understand the question. If you have other fields you want to display, either include them in another column as you have done those, or use columns.render as Kevin notes above to build a string.

    @allan can I use row span in Datatables ?

  • allanallan Posts: 46,189Questions: 1Answers: 6,410 Site admin

    You can't I'm afraid. DataTables does not support either rowspan or colspan in the table body.

    @allan I mean to ask you like Row Grouping uses colspan, is there any trick like rowspan ?

  • allanallan Posts: 46,189Questions: 1Answers: 6,410 Site admin

    Nope - sorry.

    Thank You Sir For Giving Me Your Valuable Time

  • shantaram_tupeshantaram_tupe Posts: 11Questions: 1Answers: 0

    @allan sir, can I use RowGrouping for above mention Nested Object data ?

  • allanallan Posts: 46,189Questions: 1Answers: 6,410 Site admin

    Sort of. You'd need to flatten your data source array into an array that has a single entry for each row to be shown in the DataTable.
