When you add a caption to a picture or to an object, the object and the caption text are placed together in a new frame. When you add a caption to a table, the caption text is inserted as a paragraph next to the table. When you add a caption to a frame, the caption text is added to the text inside the frame, either before or after the existing text.
向图片或对象添加标题时，对象文本和标题文本都一起放到新的框架内。向表格添加标题时，标题文本作为段落文本插入到表格内。向框架添加标题时，标题文本添加到框架的文本中，可能在现有文本之前，也可能位于当前文本之后。
