Adding Radio Buttons

Hey I was wondering if there was a way I could add a radio button or just inject my own html code into a table cell. To expand, currently I need a column to be made of selectable radio buttons so I can individually select a single row. I understand now that I can add a checkbox into a single cell/make a column of only checkboxes but I was wondering if I could do the same except with radio buttons. If any further clarification is required I am glad to provide as I understand that I may not be clear with what I am saying. Thanks.
