A Control Method of Multi-layer Header of List Control

Abstract

The invention discloses a method for controlling a list multi-layer column head. The method solves the problems in the prior art that the operation steps of the multi-layer column headers of the list control are complicated, repeated operations are many, time-consuming, and work efficiency is reduced. The method includes establishing an operation area and a display area, and a row of initial column headers is preset in the display area; the step of adding and merging column headers is performed by detecting the operation action in the operation area, and the step of deleting and merging column headers is performed by detecting the deletion action in the display area; The present invention simplifies the steps of adding and deleting multi-layer column headers, and the addition and deletion of column headers can be automatically completed through one action of the pointing device’s click-and-drag operation and deletion operation, and other column headers in the display area can be automatically lifted up according to the size of the area The lower arrangement, dynamic expansion and contraction of the height of the area, and the automatic arrangement of the relationship between the upper and lower levels of the column header greatly reduce the number of repeated operations, save the operating time of the staff, and improve efficiency.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for controlling multi-layer column headers of a list. Background technique [0002] List controls are widely used in report settings and data analysis operations. List controls generally have a multi-layer column header display form. The display form of multi-layer column headers has the following rules: each column header occupies the height of one row, and occupies one or more columns. The width of the column and the relationship between the upper and lower column headers are arranged according to the number of columns occupied, and the column headers occupying the most columns are arranged on top. However, the existing list control has the problems of complicated operation process and limited functions. [0003] Existing list controls include the following presentation methods: [0004] 1. Add a blank two-dimensional table (add several rows in advance) in th...
