(1)获取行号
<table><tr onmouseover ="showIndex(this)"><td>1</td></tr><tr onmouseover ="showIndex(this)"><td>2</td></tr><tr onmouseover ="showIndex(this)"><td>3</td></tr><tr onmouseover ="showIndex(this)"><td>4</td></tr></table>
function showIndex(pVal) {alert(pVal.rowIndex);}
(2)改变颜色、符号
/*在行上改变 图片*/for(var i=0;i<=pTable.rows.length-1;i++){var row=pTable.rows[i];row.onmouseover = function() {/*js this是事件的触发者*/this.style.backgroundColor="#ffff00";var tempDv = this.childNodes[0].childNodes[0];var currentY = parseInt(tempDv.style.backgroundPositionY.split('px')[0]);var newY = currentY - 30 + "px";tempDv.style.backgroundPositionY = newY;}row.onmouseout = function() {this.style.backgroundColor="#ffffff";var tempDv = this.childNodes[0].childNodes[0];var currentY = parseInt(tempDv.style.backgroundPositionY.split('px')[0]);var newY = currentY + 30 + "px";tempDv.style.backgroundPositionY = newY;}}
（3）excel表格效果
