<div align="left" class="table table-responsive" id="commonDvScroll">
<table id="dailySales"></table>
</div>
gross
,discount
,GST
and amount
all these are dynamic they can be 3 sometimes 2 and sometimes 1 so that I am trying to create dynamicallyHere in the below JSON I have only discount
,gst
and amount
there is no gross so in my table I only want to these three headers as col-span in my table
As solution provided by @Anilm doesn't seems to be doing like this
[{
"billdate": "2018-09-01",
"outlet": "JAYANAGAR",
"discount": 513,
"GST": 25357,
"amount": 476426
},
{
"billdate": "2018-09-01",
"outlet": "MALLESHWARAM",
"discount": 0,
"GST": 4930,
"amount": 92141
},
{
"billdate": "2018-09-01",
"outlet": "KOLAR",
"discount": 0,
"GST": 5966,
"amount": 115313
},
{
"billdate": "2018-09-02",
"outlet": "JAYANAGAR",
"discount": 471,
"GST": 28319,
"amount": 511153
},
{
"billdate": "2018-09-02",
"outlet": "MALLESHWARAM",
"discount": 0,
"GST": 6198,
"amount": 115704
},
{
"billdate": "2018-09-02",
"outlet": "KOLAR",
"discount": 0,
"GST": 4254,
"amount": 83597
},
{
"billdate": "2018-09-03",
"outlet": "JAYANAGAR",
"discount": 263,
"GST": 9944,
"amount": 167421
},
{
"billdate": "2018-09-03",
"outlet": "KOLAR",
"discount": 0,
"GST": 2693,
"amount": 53775
}
]
When in my JSON all gross
,Discount
,Gst
and Amount
are there then this will be output:
When only Discount
,GST
and Amount
are there then this will be out put:
Similarly for others also.
These four gross
,discount
,GST
and amount
are dynamic user is selecting any one,two or all then I want to populate the table.
Try like this, I have modified some code from Anilm's answer. I hope this will work for you.
