My original document has a 2-column format . After the conversion process, the document " docx " format retains the 2 columns ; however, when I want to copy , take each line of each column as a single line ; thus , the texts of the left column to right the same row are mixed . Thus , the document obtained has an original format to two columns , but when copying are NO 2 columns but one alone. This makes the document can not be obtained "format" in any other way . Any suggestions ??
