我有下面的Syncfusion JavaScript电子表格.
我在页面上有外部按钮，我想验证并突出显示按钮点击时无效的行。我该怎么做？

var sheet = [

  {
    ranges: [{
      dataSource: tradeData
    }],
    fieldAsColumnHeader: true,
    columns: [{
        width: 70
      }, {
        width: 80
      }, {
        width: 100
      }, {
        width: 100
      },
      {
        width: 70
      }, {
        width: 120
      }, {
        width: 80
      }, {
        width: 120
      },
      {
        width: 140
      }, {
        width: 80
      }, {
        width: 120
      }, {
        width: 120
      }
    ],
    rows: [{
      index: 1,
      cells: [{
          index: 3,
          value: '',
          validation: {
            type: 'List',
            value1: trade_types.toString()
          }
        },
        {
          index: 8,
          value: '',
          validation: {
            type: 'List',
            value1: counter_parties.toString()
          }
        },
        {
          index: 10,
          value: '',
          validation: {
            type: 'List',
            value1: settlement_methods.toString()
          }
        }
      ]
    }]
  }
];

var spreadsheet = new ej.spreadsheet.Spreadsheet({
  showRibbon: false,
  showFormulaBar: false,
  showSheetTabs: false,
  sheets: sheet,
  created: () => {
    //Add Data validation to range.
  }

});

spreadsheet.appendTo('#spreadsheet');

document.getElementById("btn").onclick = () => {
    // Get the data of the spreadsheet.
    //Validate data like if the cell value is null or empty, if the value is Invalid, 
    //the highlight the cell with Yellow color(Default is yellow color)
  };
