+Exported `defaultCatalogTableColumnsFunc` to create a seam for defining the columns in [CatalogTable](https://github.com/backstage/backstage/blob/master/plugins/catalog/src/components/CatalogTable/CatalogTable.tsx) of some Kinds while using the default columns for the others.
+This is useful for defining the columns of a custom Kind or to redefine the columns for a built-in Kind.

++  defaultCatalogTableColumnsFunc,

++ const myColumnsFunc: CatalogTableColumnsFunc = (entityListContext) => {
++   if (entityListContext.filters.kind?.value === 'MyKind') {

++       CatalogTable.columns.createNameColumn(),
++       CatalogTable.columns.createOwnerColumn()
++     ];
