     It is not a term in HTML (that I know of).  It is the name of an
input field, such a "CliCode".  The corresponding input control has
that name as its id.

     No, but I do put the input controls in <td>s.

     I was doing this (and appending "[0]") to get the control object.
Since Gebi()ed.

>myTables[2].tBodies[7].rows[31].cells[12].style.color = '#a00';

     I do not think of the fields by number but by name.  If I changed
their order, I would not have to change code references.

     Interesting, but not for me ATM.  My data is in input controls.

     And I have done it except I called mine Gebi().
