Get common value among Datatable rows
<p>I have a DataTable like this:</p>

<pre><code>| Supplier  | Product | Price | NewPrice | Category | Quality |
|-----------|---------|-------|----------|----------|---------|
| Supplier1 | Orange  | 100   | 105      | Food     | Good    |
| Supplier2 | Orange  | 110   | 130      | Food     | Good    |
| Supplier3 | Orange  | 200   | 250      | Food     | Good    |
</code></pre>

<p>I need a new DataRow with common values of each column</p>

<pre><code>| Supplier  | Product | Price | NewPrice | Category | Quality |
|-----------|---------|-------|----------|----------|---------|
| Supplier1 | Orange  | 100   | 105      | Food     | Good    |
| Supplier2 | Orange  | 110   | 130      | Food     | Good    |
| Supplier3 | Orange  | 200   | 250      | Food     | Good    |
|-----------|---------|-------|----------|----------|---------|
|           | Orange  |       |          | Food     | Good    |
</code></pre>

<p>How can I do this?</p>
