A problem with "Columns"--I got double columns but can't change them into a single column

Friends, my document in the word processor started out as a single column. I added a double column document to its end. Now, part of the document is double column, where I don’t want it to be. I highlight it and go to “columns” under “Format,” but even though the columns window says the highlighted space is single-column, I can’t get the program to change it from double to single column. What do I do to make it work?

You might have added a section with two columns. Turn on formatting marks to see where the section ends, View > Formatting Marks (Ctrl+F10). If you see a paragraph below the end of the section then just start typing there.
If you cannot see a paragraph mark below the end of the section then insert your cursor at the very end of the section and press Alt+Enter to begin a new paragraph after the section.

I don’t want to start typing at the paragraph marks. I want to change a double-column part of my manuscript into single-column.

Is it a table or a section? Right click in the double column part, if the context menu has Edit section then you are in a section. If at the bottom of the context menu it says Table Properties then you are in a table.
.
If you want to keep some of the text in two columns then cut the text you want in one column and paste it after the end of the the section or table.
.
If you are in a table and you want the text out of the table then either

  • select it all, copy and paste it below the table then click in the table and click in the menu Table > Delete > Table
  • Or right click in the table and click Table > Select > Table, then click Table > Convert > Table to text

.
If you want to remove the double column section entirely, right click in the section and select Edit section, in the dialogue, click the button Remove and OK. The text in the double column section will be placed in the single column.page.

Note the difference between Table and Section
