/**
 *
 *
 * 
 * The `Columns` widget displays up to 2 columns in a card or dialog. You can
 * add widgets to each column; the widgets appear in the order that they are
 * specified. For an example in Google Chat apps, see
 * [Display cards and dialogs in
 * columns](https://developers.google.com/workspace/chat/format-structure-card-dialog#display_cards_and_dialogs_in_columns).
 *
 * The height of each column is determined by the taller column. For example, if
 * the first column is taller than the second column, both columns have the
 * height of the first column. Because each column can contain a different
 * number of widgets, you can't define rows or align widgets between the
 * columns.
 *
 * Columns are displayed side-by-side. You can customize the width of each
 * column using the `HorizontalSizeStyle` field. If the user's
 * screen width is too narrow, the second column wraps below the first:
 *
 * * On web, the second column wraps if the screen width is less than or equal
 *   to 480 pixels.
 * * On iOS devices, the second column wraps if the screen width is
 *   less than or equal to 300 pt.
 * * On Android devices, the second column wraps if the screen width is
 *   less than or equal to 320 dp.
 *
 * To include more than 2 columns, or to use rows, use the
 * [`Grid`][google.apps.card.v1.Grid] widget.
 *
 * [Google Workspace Add-ons and Chat
 * apps](https://developers.google.com/workspace/extend):
 * Columns for Google Workspace Add-ons are in
 * Developer Preview.

   *
   *
   * 
   * The `Columns` widget displays up to 2 columns in a card or dialog. You can
   * add widgets to each column; the widgets appear in the order that they are
   * specified. For an example in Google Chat apps, see
   * [Display cards and dialogs in
   * columns](https://developers.google.com/workspace/chat/format-structure-card-dialog#display_cards_and_dialogs_in_columns).
   *
   * The height of each column is determined by the taller column. For example, if
   * the first column is taller than the second column, both columns have the
   * height of the first column. Because each column can contain a different
   * number of widgets, you can't define rows or align widgets between the
   * columns.
   *
   * Columns are displayed side-by-side. You can customize the width of each
   * column using the `HorizontalSizeStyle` field. If the user's
   * screen width is too narrow, the second column wraps below the first:
   *
   * * On web, the second column wraps if the screen width is less than or equal
   *   to 480 pixels.
   * * On iOS devices, the second column wraps if the screen width is
   *   less than or equal to 300 pt.
   * * On Android devices, the second column wraps if the screen width is
   *   less than or equal to 320 dp.
   *
   * To include more than 2 columns, or to use rows, use the
   * [`Grid`][google.apps.card.v1.Grid] widget.
   *
   * [Google Workspace Add-ons and Chat
   * apps](https://developers.google.com/workspace/extend):
   * Columns for Google Workspace Add-ons are in
   * Developer Preview.
