<h1>QBasic, 72 bytes</h1>

<p>Based on <a href="https://codegolf.stackexchange.com/a/167477/16766">Taylor Scott's submission</a>.</p>

<pre><code>FOR y=-8TO 8
z=ABS(y)
?"123456789abcdefghi";
LOCATE,10-z
?SPC(2*z)"
NEXT
</code></pre>

<h3>Basic explanation</h3>

<p>On each line, we print the full string <code>123456789abcdefghi</code>. Then we <em>go back</em> and overwrite part of it with spaces.</p>

<h3>Full explanation</h3>

<p>With code slightly ungolfed:</p>

<pre><code>FOR y = -8 TO 8           ' Loop for 17 rows
 z = ABS(y)               ' z runs from 8 to 0 and back to 8
 ? "123456789abcdefghi";  ' Print the full string and stay on the same line (important!)
 LOCATE , 10-z            ' Go back to column 10-z on that line
 ? SPC(2*z); ""           ' Print 2*z spaces
                          ' (SPC keeps the cursor on the same line unlesss you print
                          ' something after it, so we'll use the empty string)
NEXT                      ' Go to the next y value
