Fix PHPOffice#3988. Excel allows a table to have some colums with filter buttons exposed and some with filter buttons hidden. However you cannot do this in "native" Excel - VBA is required for this feature. PhpSpreadsheet is supposed to be able to handle this, but Xlsx/Writer/Table had a bug. The `filterColumn` tags in the xml should be children of the `autoFilter` tag, but were generated as siblings. Moving one statement fixes that problem. Fixing that exposed another problem - autoFilter `showHideRows` was not properly recognizing that a filter could exist without any rules, which is what happens when a table filter button is hidden. Another simple change fixes that problem. The parent issue correctly points out the problem for Column D in samples/Table/01_Table. However, that sample also has a problem with Column A - unlike columns B and C, there is a filter appled to column A, so its dropdown button should appear different than those in B and C. That problem is also corrected with the fixes above. I also added some formal tests based on that sample.
