如何用VBA宏实现Excel数据生成PPT并动态适配内容至幻灯片？

原代码存在以下核心问题导致格式异常和内容溢出：

1. 强制每页仅显示1行数据，未合理利用幻灯片空间
2. 表格高度固定，内容过长时直接溢出单元格
3. 未开启文本自动换行，长文本无法自适应列宽
4. 列宽分配逻辑未考虑实际内容长度，部分列过窄导致内容挤压

修改后的VBA代码 #

关键改进点 #

• 动态行数分配：通过计算幻灯片可用高度，自动确定每页可放1-3行数据，最大化利用空间
• 文本自动换行：所有单元格开启WrapText = True，长文本自动换行避免溢出
• 自适应行高：数据行高度根据内容自动调整，不会出现内容被截断或留白过多
• 优化列宽逻辑：优先保证"Issue Summary"列的宽度（最小200），其他列设置合理最小宽度，避免内容挤压
• 批量处理数据：一次性填充多行数据，减少幻灯片创建次数，提升运行效率
• 边距预留：幻灯片上下左右预留边距，避免表格贴边影响美观
