@angun33 Looks like version >= 10.0.0 only work with Angular 5. If you want to use Angular 4 with no warning from Angular cli, then you must use ngx-datatable 9.3.0 or less.

Hi @wizarrc / @jasonhjohnson / @dinvlad

I update the typescript version and using angular 4, and its working like magic for me…

Below is the tweaks I did

npm install typescript@latest --save-dev
...
├─┬ @angular/cli@1.3.2
│ └── typescript@2.4.2
└── typescript@2.5.3

└── @swimlane/ngx-datatable@10.2.3

And I added both name and prop attributes in column configuration, below is the snippet

{ name: 'Symbol', prop: 'SYMBOL' },
{ name: 'Trade', prop: 'TRADE' },
{ name: 'Price #1', prop: 'PRICE_1'},
{ name: 'Date #1', prop: 'DATE_1' },
{ name: 'Price #2', prop: 'PRICE_2'},
{ name: 'Date #2', prop: 'DATE_2' },
{ name: 'Cash Futures', prop: 'CASH_FUTURES' },
{ name: 'Exchange', prop: 'EXCHANGE' }
