It's an array that sets, for every grid column, what data-set fields utilize to indicate data-fields that intervene in filter operations, associated to the relative column position
(values with an index equal to 0 are associated to the leftest column than the grid,thats with an index 1
to the first column on the right than the previous column, and so on till the latest index,
because for a N column grid, are required N rows of this array).
| ArrayFilter = | [["dataField0","dataType0",id_dataField0],["dataField1","dataType1",id_dataField0],...,["dataFieldN-1", "dataTypeN-1",id_dataField0]] |
| dataField | String with the field name associated to the grid column for the filter. |
| dataType | Char that indicate the type of data for the filter-column: "N" = Number "S" = String "B" = Boolean "D" = Date |
| id_dataField | Number which indicate the id of the field contained in the output of the .php file set by the dataUrl parameter for the relative column filter working. |
