- As per requirnment
gross,discount,GSTandamountall these are dynamic they can be 3 sometimes 2 and sometimes 1 so that i am trying to create dynamically - I have commented the lines in my code where i am creating these as headers
EDIT here 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",
