These are the Excel tables that @ianb is talking about: https://support.microsoft.com/en-us/office/overview-of-excel-tables-7ab0bb7d-3a9e-4b56-a3c9-6c94334e492c
LibreOffice does have a "Tables" menu entry. But that refers to adding another sheet to your workbook; it does NOT provide functionality analogous to Excel´s tables. And I agree that those are an important feature.
In happier news, LibreOffice definitely does have pivot tables.
