setColumns^{(columns: Array)}

Set new columns for grid.

For proper work it is recommended to set id-s or unique data indexes for columns.

Example:

var grid = new FancyGrid({
  ...
...
grid.setColumns([
  type: 'select'
},{
  type: 'rowdrag'
},{
  title: 'Company',
  index: 'company',
  type: 'string',
  autoWidth: true
},{
  title: 'Price',
  index: 'price'
},{
  title: 'Change',
  index: 'change'
},{
  title: '% Change',
  index: 'pctChange'
},{
  title: 'Last Updated',
  index: 'lastChange',
  type: 'string',
  width: 150
},{
  title: 'Company + Price',
  id: 'companyPrice',
  render: function(o){
    o.value = o.data.company + ' ' + o.data.price;
    
    return o;
  }
}]);
