如何在reactjs中添加json数组

Question

I'm new to reactJS and I need to achieve a certain result. I have an array-

{
  "column_01": 11,
  "column_02": 123,
  "column_03": "TEST0001.iml",
  "column_04": "TEST0001.qsl",
  "column_05": "2018-11-13 01:04:40",
  "column_06": "PASSED",
  "column_07": "4/0/4"
}

I need to add another set similar structure to that data and add up these to an array, such result should be:

{
  "column_01": 11,
  "column_02": 123,
  "column_03": "TEST0001.iml",
  "column_04": "TEST0001.qsl",
  "column_05": "2018-11-13 01:04:40",
  "column_06": "PASSED",
  "column_07": "4/0/4"
},
{
  "column_01": 12,
  "column_02": 124,
  "column_03": "TEST0001.imx",
  "column_04": "TEST0001.qsx",
  "column_05": "2018-11-13 01:04:40",
  "column_06": "PASSED",
  "column_07": "4/0/5"
}

…. how do I achieve that to in react js? so far these are my efforts but haven't succeed yet:

onTableViewChange(result){
    const arr = [];
      if (result) {
          console.log(result.original);
          arr.push(result.row);
     }

You haven't provided a lot of details, but arr should be defined in your state, and then you should update it using setState like this

this.setState(prevState => { 
  return { arr: [...prevState.arr, result.row] }
})
