Add yours needed in the crystal report
Since some of the more large reports are often encountered, some of which are needed, some do not need, some of this need, will not need it next time, it is impossible to consider all the statements, so Dynamic add fields need to be dynamically reported. Doing a dynamic report mainly uses a custom formula in the crystal report, first add N custom formula in the report (where n is the most possible number of fields), and set up the line between the lines in the design report. Distance, there is a width of the text object, the width of the custom formula. Figure:
