How to make HTML table expand on click?

Question

I am rendering HTML table with the help of JavaScript. I have made the table successfully, but now I have one requirement to show some new data in a row like on click expand row

Table functionality:

• I am populating my table Some brand wise each brand has some items inside them, which I want to show when the brand is clicked
• I almost created the table, but not able to create the expandable row
• My one of column is populating wrong data also

In my code I have commented all the lines what I am doing at which line

Issues I am facing

• I have already commented the line where I am calculating netamount to populate inside tbody as GRN entery brand wise but that's causing the issue

I have created two code snippets one as full static HTML like what I want, and a second to show what I have done.

The help I have found on Google

  <table id="ConsumptionTable"></table>
</div>

I have tried the other approach, which was when the user clicks on any brand I was making an Ajax call and running the query on the basis of that brand name and getting data, but still not able to get the expand functionality.

Now I realised that this is the best approach to get the data at once, then make table with that; I am just struggling to get it right

Dynamic Code Working process

• Currently I have table with Brand Name,Grn Entery,Sales Sales body data which is in percentage I am calculating it by dividing grn by Total grn of that column and dividing it by 100
• So when user clicks on any brand names's icon that is plus in my case I want to expand rows with all itemnames of that brand and whole structure of table will be same as it is for brandname wise, grn calculation wil all be according to item name, currently it is as per brand name

Edit/update

I am having some issues:

• First of all using this code I am geting brand names and item names but it is taking NA also, I have tried to filter it out but haven't succeeded. Please check my snippet, I have commented all lines there.

• when there is transactiontype:sales and itemname and brandname= NA then I am populating those values in header as sales value they don't have any relation with calculating percentage

• when I am populating the item inside brand there I have to do it dynamically I have tried but didn't get that

Answer 1

I suggest you use DataTables.

DataTables offers a rich API for rendering row data, show/hiding columns, search/filter, paging, etc. It can be styled through jQuery UI or Bootstrap, or your own branding. In contrast to writing up your own table display logic, the DataTables libraries are free to use and extremely flexible.
