Note that the code could use some cleaning. Just like the C++ example, this too is in generalized form.
It uses C's printf to reduce the number of imported modules. In order to use std.stdio.writefln, all "%.*s" should be converted to "%s" (but NOT "%*d").
<lang d>import std.string;
void printTable(uint minsize, uint maxsize)
{
uint maxlen = toString(maxsize * maxsize).length;
uint x, y;
char[] hline = new char[](maxlen);
hline[] = '-';
char[] hspace = new char[](maxlen);
hspace[] = ' ';
for(x = minsize; x <= maxsize+1; x++)
printf("+%.*s", hline);
printf("+\n|%.*sx%.*s", hspace[0..$/2], ((hspace.length % 2) == 1) ? hspace[0..$/2] : hspace[0..$/2-1]);
for(x = minsize; x <= maxsize; x++)
printf("|%*d", maxlen, x);
printf("|\n");
for(x = minsize; x <= maxsize+1; x++)
printf("+%.*s", hline);
printf("+\n");
for(y = minsize; y <= maxsize; y++)
{
printf("|%*d", maxlen, y);
for(x = minsize; x <= maxsize; x++)
{
if(x >= y)
printf("|%*d", maxlen, x * y);
else
printf("|%.*s", hspace);
}
printf("|\n");
}
for(x = minsize; x <= maxsize+1; x++)
printf("+%.*s", hline);
printf("+\n");
}
void main()
{
printTable(1, 12);
}</lang>
