What you can do there is use map method to create an array of objects where each object contains the desired columns from each row. {{table2.data.map(x => ({ name: x.name, id: x.id, column1: x.column1, column2: x.column2 }))}}
map
{{table2.data.map(x => ({ name: x.name, id: x.id, column1: x.column1, column2: x.column2 }))}}
