Claim:
1. A data display method for an energy management system, the data display method comprising: receiving, via a user input unit, a table generation request including a base key value which is a data name of the table; receiving, via the user input unit, selection information in a table display form configured for generating a hierarchical table and selection information of sorting the data; receiving, via the user input unit, a selection of a plurality of layers of the table display form; reading, by a control unit, data to be included in the hierarchical table; generating, via a table generation unit, the hierarchical table for the data according to the selection information in the table display form according to control by the control unit; sorting, by the control unit, the data according to the input to the plurality of layers of the table display form; displaying the sorted data of the hierarchical table in a display unit; receiving, via the user input unit, a sorting request input for the displayed data; and re-sorting, by the control unit, the displayed data based on the received sorting request input, and displaying the re-sorted data in the display unit; and wherein the hierarchical table comprises the plurality of layers including an uppermost layer to a lowermost layer and the uppermost layer corresponds to a first hierarchical table comprising a plurality of data, and re-sorting the displayed data comprises: sorting the plurality of data of the first hierarchical table; displaying the sorted first hierarchical table in the display unit in response to the sorting request input for the plurality of data of the first hierarchical table; displaying data of a lower hierarchical table at a lower position in correspondence with a sorting order of the first hierarchical table when the plurality of data of the first hierarchical table are sorted; and re-sorting data of the lower hierarchical table when a re-sorting request input for data of the lower hierarchical table is received and displaying the re-sorted data.
