document.getElementById('myTable').style.backgroundColor = 'lightblue';

var row = document.getElementById('rowId');
row.style.backgroundColor = 'yellow';

var cell = document.getElementById('cellId');
cell.style.backgroundColor = 'green';

function highlightRow(rowId) {
    var row = document.getElementById(rowId);
    if (row) {
        // 假设我们要根据某个条件来改变颜色
        var shouldHighlight = true; // 这里应该是你的逻辑判断
        row.style.backgroundColor = shouldHighlight ? 'red' : '';
    }
}
