[Solved]-D3 how to properly get the key value INSIDE of a json object-d3.js

var data = [{
    "Label": "External-Partner-Induced",
    "Count": 9
  },
  {
    "Label": "Null",
    "Count": 1
  },
  {
    "Label": "FCTS-Induced",
    "Count": 66
  },
  {
    "Label": "EI-Partner-Induced",
    "Count": 78
  }
];

function tabulate(data, columns) {
  var table = d3.select('body').append('table')
  var thead = table.append('thead')
  var tbody = table.append('tbody');

  // append the header row
  thead.append('tr')
    .selectAll('th')
    .data(columns).enter()
    .append('th')
    .text(function(column) {
      return column;
    });

  // create a row for each object in the data
  var rows = tbody.selectAll('tr')
    .data(data)
    .enter()
    .append('tr');


  // create a cell in each row for each column
  var cells = rows.selectAll('td')
    .data(function(row) {
      return columns.map(function(column) {
        return {
          column: column,
          value: row[column]
        };
      });
    })
    .enter()
    .append('td')
    .text(function(d) {
      return d.value;
    });
  return table;
}
// render the table
tabulate(data, d3.keys(data[0]));
