Display SharePoint List or Library in Data table

Introduction:
Today we are going to learn an interesting article of how to use DataTables.js JQuery 🔗 in SharePoint(2013, 2016, Online - O365).
Since SharePoint 2013 has released, the way how the data is created, updated & displayed has changed a lot - I mean Client Side scripting has become more powerful. Server Side Coding in SharePoint (JSOM - Java Script Object Model) has the following uses or advantages over server side coding which are:
1. Faster data rendering
2. Easy to debug from browser
3. Easy & faster validation response to end users
4. Just add a content editor web part and add the code 😁
5. No IIS reset required
6. Just use client desktop and no SharePoint installation required
7. No Visual Studio (why spent extra money on license?😎)
8. Just use a Editor to write and format the code.
💡 I have recently started using Microsoft Visual Studio Code. Give a try, you will never use other editors. What a powerful editor! Download from this link and it is FREE 🔗
Scenario:
What if you were given a task to display a list or a library in a SharePoint page which has 1000's of records in it. Also, it has to load faster, need a free text search, paging features, etc.? But you have no server side access for coding or server deployments allowed 😜
Solution: 
Obviously, any SharePoint developer will go for the option SharePoint Java Script Object Model (JSOM). But how to create a table, searchable content, etc. DataTables.JS is a Table plug-in for JQuery. It is used for display the HTML content as Table.
Let's not wait and create a custom SharePoint list(here named it as Finance Sample Data). Download the data used for this example here 🔗
This is how the logic/solution for this scenario is implemented:
1. Upload the JQuery, DataTable.JS, CSS, Images required in Site Assets Library(best practice in SharePoint)
2. Create a simple text file in which add the reference to JS, CSS, Images, etc. Then add the DIV tags for creating a section and then add a TABLE tag for displaying the content, then document.ready() function and finally custom JS functions. You can also have HTML file and JS files separately.
3. In document.ready(), call the custom function which will query the data using CAML query (I haven't tried using REST API since there will be an issue when you query 1000 items at a time or when paging is enabled, if you have any thoughts share it in the command), load the JSON data as HTML tags and draw a data table using the data objects.

        //Bind the HTML data to the Table

        tableFinanceReport = $('#idFinanceReportList').DataTable(

                "columnDefs": [
                    { "targets": [0], "visible": true, "width": "15%" },
                    { "targets": [1], "visible": true, "width": "8%" },
                    { "targets": [2], "visible": true, "width": "8%" },
                    { "targets": [3], "visible": true, "width": "8%" },
                    { "targets": [4], "visible": true, "width": "8%" },
                    { "targets": [5], "visible": true, "width": "8%" },
                    { "targets": [6], "visible": true, "width": "8%" },
                    { "targets": [7], "visible": true, "width": "8%" },
                    { "targets": [8], "visible": true, "width": "8%" }
                ]
            }
        );

        tableFinanceReport.draw();
    }
    function failed(sender, args) {
        alert("Data Reterival Failed: " + args.get_message());
    }

</script>

4. Now upload the text file either in a Document Library or preferably in Site Assets. Create a SharePoint page and then add a Content Editor web part. Refer the text file in the Content Editor web part and save it. That's it, we will see a very nice Table rendering the data as shown below:
5. The DataTables.JS has inbuilt functionalities which are listed below:
  • Free text search option (very fast)
  • Abililty of change the number of records display (25, 50, 100..)
  • Paging with Previous and Next options
  • Displays the number of items displayed and also changes the number according to paging
  • Ability to sort the columns both ascending & descending
  • Ability to query a column but hide it from view - if that specific column is required for internal data rendering logic or comparison or etc.
Cool, isn't it? 
Download the Custom List Template with contents (.STP file), JS files, images, text file which has the entire code from this link.🔗
