### 🚑 其他信息


Start at the ProTable entry point and reproduce the report using a columns configuration with 16–18 columns, comparing the rendered table with the attached screenshot. Trace the column rendering and layout behavior to identify why columns are duplicated. Done means the same column counts render each column exactly once.
