C# delete column from datatable where all values are zero
<p>I need to delete columns from datatable where all rows have 0 for value. Or in other words, where sum is 0. </p>

<pre><code>1 2  5   99.9 442.25 221 0
1 2 77.7 889  898     55 0
9 0 66   42    55      0 0
</code></pre>

<p>In this example, last column should be removed.</p>

<p>How to do this?</p>
