<body>
<%
StringBuffer sb = new StringBuffer();
for(int i = 1; i <= 9; i++){
for(int j = 1; j <= i; j++){
sb.append(j + "*" + i + "=");
sb.append(j*i);

</body>
第二种：
<body>
<%
for (int i = 1, j = 1; i <= 9; i++, j++) {
if (j <= i) {
out.print(i + "*" + j + "=" + i * j + " ");
i--;
} else {
j = 0;
out.print("<br/>");
}
}
%>
</body>
