Placeholder text for the field. This can be a simple string or a reference to a value in the current record or another one. With a syntax like __row|field the placeholder will take the value of the given field from the current record.

This can be recursive to follow a longer path in a table record chain. If the designated field is a relation to another table (is of type select, group or inline), the related record will be loaded and the placeholder searched within it.

Example from the "sys_file_reference" table:

  'title' => [
      'l10n_mode' => 'prefixLangTitle',
      'exclude' => true,
      'label' => 'LLL:EXT:core/Resources/Private/Language/locallang_tca.xlf:sys_file_reference.title',
      'config' => [
          'type' => 'input',
          'size' => 20,
          'max' => 255,
          'nullable' => true,
          'placeholder' => '__row|uid_local|metadata|title',
          'mode' => 'useOrOverridePlaceholder',
          'default' => null,
      ],
  ],

In the above placeholder syntax, uid_local points to the related "sys_file" record and metadata points to the "sys_file_metadata" of the related "sys_file" record. From there we take the content of the title field as placeholder value.
