Find and highlight text within specific elements.

Find and highlight text within specific elements.

I would like to do a search through a specific column of a table. When a letter matches a search string it will be highlighted.

For example the following table

xxx xxx xxx abc
xxx xxx xxx bcd
xxx xxx xxx xyz

I want to do a search for b in the last column. When found the background of that specific letter changes.

xxx xxx xxx abc
xxx xxx xxx bcd
xxx xxx xxx xyz

Is this even possible?
