Description

export const paginationProps = buildProps({
  layout: {
    type: String,
    default: (
      ['prev', 'pager', 'next', 'jumper', '->', 'total'] as LayoutKey[]
    ).join(', '),
  },
});

Thank your contribution.

but props default information matches the documentation information, so no changes are required.

was my fault, didn't notice that was the default value, I thought it was an optional parameter
