e. On-line real-time report modification and data screening, especially for explaining experience and knowledge content, needs to remove some improper explanation descriptions.
After the user previews all the contents to be output to the logging interpretation report on line, the whole report contents can be edited. The embodiment of the invention provides interactive operation, for example, screening partial table data, wherein some contents need the support of other data, can be directly loaded from a database, and can remove some improper description of the processing interpretation result picture, and can recall the drawing to re-intercept a new interpretation result picture to be inserted into a specified position, thereby completing the report in real time on line.
f. All report configurations and contents are saved, and a com component interface of Word is called to automatically generate a logging interpretation report.
