What if the Word document layout doesn't harmonize?
In this case, the workaround is simple, select the paragraph that is distorted by the line, and then open the paragraph panel and uncheck the check boxes that precede the "if the document grid is defined, Snap to Grid", and then make sure that the document spacing becomes normal.
There is also a situation, often a Word document the last page, only a few lines of words, printing out very paper, but also not good-looking. Generally by adjusting the font size, spacing, spacing, etc. to solve, very few. There's actually a better way.
In Word 2016, go to the file → options open Options dialog box, select the Quick Access Toolbar on the left, set the common commands to all commands, and then find the "reduce one page" item in the list, and click Add to add it to the Quick Access Toolbar, when you need to quickly indent the page, Click on some of this button to reduce the purpose of a page, and the layout is not much change.
