如何使用javascript函数生成HTML表格？

var tableContainer = document.createElement('div');

var table = document.createElement('table');
tableContainer.appendChild(table);

var headerRow = table.insertRow(0);
var headerCell1 = headerRow.insertCell(0);
headerCell1.innerHTML = "Header 1";
var headerCell2 = headerRow.insertCell(1);
headerCell2.innerHTML = "Header 2";

for (var i = 0; i < data.length; i++) {
  var dataRow = table.insertRow(i+1);
  var cell1 = dataRow.insertCell(0);
  cell1.innerHTML = data[i].column1;
  var cell2 = dataRow.insertCell(1);
  cell2.innerHTML = data[i].column2;
}

document.getElementById('tableContainer').appendChild(tableContainer);
