Column height is determined by the taller column, and widths can be customized. If the screen is too narrow, the second column wraps below the first, with specific pixel/point/dp thresholds for web, iOS, and Android devices. Key actions include adding columns using `addColumn()` and controlling resizing with `setWrapStyle()`. These features are available for Google Chat and Workspace add-ons.\n"],null,["# Class Columns\n\nColumns\n\nThe [Columns](#) widget displays up to 2 columns in a card or dialog. You can add widgets to\neach [Column](/apps-script/reference/card-service/column); the widgets appear in the order that they are specified. For an example in\nGoogle Chat apps, see [Columns](https://developers.google.com/workspace/chat/format-structure-card-dialog#display_cards_and_dialogs_in_columns).\n\nThe height of each column is determined by the taller column. For example, if the first column\nis taller than the second column, both columns have the height of the first column. Because each\ncolumn can contain a different number of widgets, you can't define rows or align widgets between\nthe columns.\n\nColumns are displayed side-by-side. You can customize the width of each column using the\n[HorizontalSizeStyle](/apps-script/reference/card-service/horizontal-size-style) field. If the user's screen width is too narrow, the second column\nwraps below the first:\n\n- On web, the second column wraps if the screen width is less than or equal to 480 pixels.\n- On iOS devices, the second column wraps if the screen width is less than or equal to 300 pt.\n- On Android devices, the second column wraps if the screen width is less than or equal to 320 dp.\n\nAvailable for Google Chat apps and Google Workspace add-ons. The add-on UIs that support\ncolumns include:\n\n- The dialog displayed when users open the add-on from an email draft.\n- The dialog displayed when users open the add-on from the **Add attachment** menu in a Google Calendar event. \n\n ```javascript\n // Build a column that is aligned in the center and fills the space:\n const column =\n CardService.newColumn()\n .setHorizontalSizeStyle(\n CardService.HorizontalSizeStyle.FILL_AVAILABLE_SPACE)\n .setHorizontalAlignment(CardService.HorizontalAlignment.CENTER)\n .setVerticalAlignment(CardService.VerticalAlignment.CENTER);\n const columns = CardService.newColumns().addColumn(column).setWrapStyle(\n CardService.WrapStyle.WRAP);\n``` \n\n### Methods\n\n| Method | Return type | Brief description |\n|-----------------------------------------------------|--------------|--------------------------------------------------------------------------------------------|\n| [addColumn(column)](#addColumn(Column)) | [Columns](#) | Adds a [Column](/apps-script/reference/card-service/column) to the Columns widget. |\n| [setWrapStyle(wrapStyle)](#setWrapStyle(WrapStyle)) | [Columns](#) | Sets the wrap style of the columns, controls how the column resizes based on screen width. |\n\nDetailed documentation\n----------------------\n\n### `add``Column(column)`\n\nAdds a [Column](/apps-script/reference/card-service/column) to the Columns widget.
