複製代碼代碼如下:
function hb(){
var tab = document.getElementById("subtable");
var maxCol = 3, val, count, start;
var ys="";
for(var col = maxCol-1; col >= 0 ; col--) {
count = 1;
val = "";
for(var i=0; i<tab.rows.length; i++){
if(val == tab.rows[i].cells[col].innerHTML){
count++;
}else{
if(count > 1){
//合併
start = i - count;
if(ys=="#00FFFF"){
ys="#EEEE00";
}else{
ys="#00FFFF";
}
tab.rows[start].cells[col].rowSpan = count;
tab.rows[start].cells[1].style.backgroundColor=ys;//改變顏色
// ys="#EEEE00";
// tab.rows[i].cells[1].style.backgroundColor="#00FFFF";//改變顏色綠色
for(var j=start+1; j<i; j++){ //
tab.rows[j].cells[col].style.display = "none";
tab.rows[j].removeChild(tab.rows[j].cells[col]);
}
count = 1;
}
val = tab.rows[i].cells[col].innerHTML;
}
}
if(count > 1 ){ //合併，最後幾行相同的情況下
start = i - count;
tab.rows[start].cells[col].rowSpan = count;
for(var j=start+1; j<i; j++) {
tab.rows[j].removeChild(tab.rows[j].cells[col]);
}
}
}
}
