Hello, I have text in Word. there 5 lines go one under the other in a column, then an indent of a centimeter by 4 and again 5 lines. There are a lot of such columns, so here's how to make the lines shuffle but only in their own column. that is, so that in 1 column 5 lines are mixed with each other, in another column 5 lines are also mixed only with each other. Help me please!!!
