(1)获取行号

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;
            }
        }
