Goal: To realize a complex table with the following functions: expand table rows, expand all, collapse, collapse all; dynamically configure which columns to display, adjust the display order of columns; dynamically adjust row order, move up, move down, row Move topmost, line move bottommost
1. Page effect:
1. Expand all
2. Put all away
3. Configure display columns
4. Adjust the field order (drag and drop)
5. Row operation (view, modify, delete, move up and down the row)
2. Code implementation (vue+Element-ui)
Idea: In essence, the table is regarded as an array, and the operation on the table is regarded as the operation on the array.
