用循环结构输出图形

                       1
                      121
                     12321   
                    1234321
                   123454321
                  12345654321
                 1234567654321
                123456787654321
               12345678987654321
    你好，我想打出来的是这个图形，中间的数最大，数字居中，呈一个塔型，能不能帮我看一下下面的代码，为啥后面的数不会减小?
 #include<stdio.h>
int main()
{                                                                        
    int i,j,n;                                                      
    printf("请输入所需要打印的行数：");                     
    scanf("%d",&n);                              
    for(i=0;i<n;i++)                                            
    {                                                         
        for(j=n-1;j>i;j--)
        printf(" ");
        for(j=0;j<i;j++)
        printf("%d",1+j);
        for(j=i;j<2*i-1;j++)
        printf("%d",i-1);
        printf("\n");
    }
return 0;
 }  
              输出的图形为：
                       1
                      121
                     12322
                    1234333
                   123454444
                 。。。。。。。
                                 为啥会出现这种情况？能帮忙解决，在下真是感激不尽
