错在哪了，都好几天了，显示123的程序

#include <reg52.h>
sbit dula=P2^6;
sbit wela=P2^7;
void delay(unsigned int t);
unsigned char code table[]={
0x3f,0x06,0x5b
};
void main()
{
while (1)
{
dula=1;
P1=table[1];
dula=0;
P1=0xff;
wela=1;
P1=0xfe;
wela=0;
delay(50);

dula=1;
P1=table[2];
dula=0;
P1=0xff;
wela=1;
P1=0xfd;
wela=0;
delay(50);
dula=1;
P1=table[3];
dula=0;
P1=0xff;
wela=1;
P1=0xfb;
wela=0;
delay(50);
}
}
void dylay(unsigned int t)
{
while(--t);
}
大侠们帮帮我把，都郁闷死了
