How to underline or color text in a cell

Hello,I have a cell array like this cell={'hello','i','a','123','e'}.How could I determine specific cell elements by coloring or underlining? for example I want to specify cell{1}='hello' using underline.thanks

@Fateme Jalali: do not get confused about what text data is:

• character arrays store only the character number. This encodes what character it is. But it does not encode any information about the typeface (font), the size, the slant, the color, the location, the orientation, the location, the visibility, or anything else that you might dream of.
• Formatted text (such a Word document, a PDF, or a rendered HTML page) includes lots of meta information about the formatting of the text: colors, shape, etc.

Even this website sends all of the text as simple character codes, and separately sends information about location, color, font, etc for displaying that text.

Do not confuse text data with formatted text.

You cannot do that. Cell arrays do not have formatting properties. Color and underline are something that happens at display time; you might be able to set your cells so that they display the way you want, but it depends upon how you are doing the displaying.

Is there any way to store elements of a cell in a text file and show underlined results in a text file?

No. Text files do not have formatting attributes such as color and underline.

Documents might have formatting, but those are effectively binary data structures or effectively code written in a programming language such as HTML or RTF or PostScript, and it is the rendered version of them that display the color or underline.
