# How To: Conditionally Show/Hide Table Columns

Use conditional column logic when a table should adapt to the current record.

### Problem

You want certain columns to appear only when specific conditions are met.

### Solution

**Hide Column for Closed Opportunities:**

```
<column showcolumn="{{!Opportunity.StageName}} != 'Closed Won'">Expected_Close_Date__c</column>
```

**Show Column for Specific Stages:**

```
<column showcolumn="({{!Opportunity.StageName}} == 'Prospecting' || {{!Opportunity.StageName}} == 'Qualification')">Next_Step__c</column>
```

**Complete Example with Headers:**

```
<table>
  <thead>
    <tr>
      <th>Product</th>
      <th>Price</th>
      <!--RENDER='{{!Opportunity.Type}}' == 'New Business'-->
      <th>Discount</th>
      <!--ENDRENDER-->
    </tr>
  </thead>
  <tbody>
<!--{{!
<lineitems>
<listname>opportunitylineitems</listname>
<column>PricebookEntry.Product2.name</column>
<column prefix="$" format-number="#,###.##">unitprice</column>
<column showcolumn="{{!Opportunity.Type}} == 'New Business'" postfix="%">Discount</column>
</lineitems>
}}-->
  </tbody>
</table>
```

### Operators You Can Use

| Operator | Meaning    | Example                                      |
| -------- | ---------- | -------------------------------------------- |
| `==`     | Equals     | `{{!Opportunity.StageName}} == 'Closed Won'` |
| `!=`     | Not equals | `{{!Opportunity.Type}} != 'Renewal'`         |
| \`       |            | \`                                           |
| `&&`     | AND        | `(condition1 && condition2)`                 |

### Tips

* Apply the same condition to the header with `RENDER` tags.
* Wrap OR and AND expressions in parentheses.
* The column hides when the condition returns `false`.
* Test with different record states before rollout.
