我写个，不过你说的外部RAM 我不知道你指的是哪个。所以我就么写，
#include<reg51.h>
#define uchar unsigned char
uchar *p;
uchar code table[]={0x21,0x23,0x25,0x26,0x27,0x28,0x29,0x22,0x31,0x33,0x35,0x36,0x37,0x38,0x39,0x32,0x50,0x51,0x52,0x53,0x55,0x56,0x57,0x58,0x69,0x98,0x85,0x76,0x92,0x83,0x65,0x66};
P2 = 0x40;
p=table;//指针p 指向表table 首地址。就相当于把表格整个赋值给P了，P 可以直接指向外部RAM;

#include<reg51.h>
#include <absacc.h> /* Include Macro Definitions */

#define uchar unsigned char
#define ext_ram XBYTE[0x0000] //程序存储器中表的内容送入外部RAM单元
,外部RAM地址0000

uchar code TAB[]={0x21,0x23,0x25,0x26,0x27,0x28,0x29,0x22,0x31,0x33,0x35,0x36,0x37,0x38,0x39,0x32,0x50,0x51,0x52,0x53,0x55,0x56,0x57,0x58,0x69,0x98,0x85,0x76,0x92,0x83,0x65,0x66};

main()
{
uchar i;
for (i=0;i<33;i++)
ext_ram=TAB[i];
while(1);
}
