And here's my code:
Switch(

"ID",
SortByColumns(
Filter(
RestockProduct,
StartsWith(
Title,
txt_NameFilter_2.Text
) && ( Status.Value = cmb_StatusRestock.Selected.Value || cmb_StatusRestock.Selected.Value = Blank()), DateRestock >=dpFrom_1.SelectedDate && DateRestock <= dpTo_1.SelectedDate
),
"ID",
If(varSortDirection=SortOrder.Ascending,SortOrder.Ascending,SortOrder.Descending)),
"Title",
SortByColumns(
Filter(
RestockProduct,
StartsWith(
Title,
txt_NameFilter_2.Text
) && (Status.Value = cmb_StatusRestock.Selected.Value || cmb_StatusRestock.Selected.Value = Blank()), DateRestock >=dpFrom_1.SelectedDate && DateRestock <= dpTo_1.SelectedDate
),
"Title",
If(varSortDirection=SortOrder.Ascending,SortOrder.Ascending,SortOrder.Descending)),
"QuantityRestock",
SortByColumns(
Filter(
RestockProduct,
StartsWith(
Title,
txt_NameFilter_2.Text
) && (Status.Value = cmb_StatusRestock.Selected.Value || cmb_StatusRestock.Selected.Value = Blank()), DateRestock >=dpFrom_1.SelectedDate && DateRestock <= dpTo_1.SelectedDate
