There will be a line under any text typed in the table cell. Select the 'Strikethrough' icon in the 'Fonts' section.
Share them with others and work together at the same time.
On the right hand side of the dialog box, use the controls to add the border to both the left and right sides of your paragraph. Select the text that you want to strikethrough. When a paragraph or line of text is too long to fit on one line, web browsers, like many other programs, automatically wrap the text to the next line.
