# Sample 4. Step 7: Table column names, TableHeader group

> Prepare for table detection by creating a TableHeader group of Static Text elements that find the invoice table column names on the first page.

Use a [Table](/flexi-capture/fls/tables/general-tables) element to search for the **Invoice Table** field. First, though, detect the column names, because this sample uses auxiliary elements to find them.

Create the column-name descriptions in a **TableHeader** group, and limit the search area to the first page.

## Create the TableHeader group

<Steps>
  <Step title="Create the Group element">
    In the tree of elements, create a [Group](/flexi-capture/fls/template/elements-compound) element and name it **TableHeader**.
  </Step>

  <Step title="Specify the search area">
    Click the **Search Constraints** tab and specify the search area for the element:

    * Select the **Absolute search area constraints** option.
    * In the **Pages** field, select **Range** from the drop-down list.
    * In the **Range** field, type `1`.
    * In the **Region** field, keep the default value.
    * Click **Add...**.
  </Step>
</Steps>

In the TableHeader group, create the following [Static Text](/flexi-capture/fls/template/static-text) elements to search for the column names:

| Element           | Detects                       | Described in                                      |
