Tableau's Filters

The tableau filter is set to be understood as private and global, and can be set to be valid only for the current worksheet, that is, a private filter that allows you to filter the data for a user-specific requirement, to set several worksheets to be valid, or to set all worksheets for this data source, the global filter, such as
