如何在jqGrid.Is中动态使用“格式化程序”呢？

$("#grid").jqGrid({
  url: "data.json",
  datatype: "json",
  colModel: [
    { name: "id", label: "ID", width: 50 },
    { name: "name", label: "Name", width: 100 },
    { name: "age", label: "Age", width: 50 },
    { name: "gender", label: "Gender", width: 50 },
    {
      name: "salary",
      label: "Salary",
      width: 100,
      formatter: function(cellValue, options, rowObject) {
        // 自定义格式化程序
        var formattedValue = cellValue.toFixed(2); // 保留两位小数
        return "<span style='color: red;'>" + formattedValue + "</span>"; // 使用红色字体显示
      }
    }
  ],
  rowNum: 10,
  rowList: [10, 20, 30],
  pager: "#pager",
  viewrecords: true,
  caption: "Employee Data"
});
