Thanks for your response, but your examples are the same kind of thing
I was encountering in the few sources that addressed amending.  It did
not address the issue of "drilling down" into the middle of a table
and changing a value.

There are 3 levels of data: table (called "data"), row, and column.
Thus, every box of the table has a 3-part address.  Your example does
not indicate how to change a single cell in a table.  The diagram
below (sorry, I can only do a proportional font) shows the beginning
of the transposed data:

┌───────┬───────┬──────┬─┬──────┬───────┬─
│261.78      │263.33       │263.27    │0│263.23    │264.22      │
├───────┼───────┼──────┼─┼──────┼───────┼─
│264.02      │264.59       │263.47    │0 │264.87   │265.17      │
├───────┼───────┼──────┼─┼──────┼───────┼─
│261.54      │262.54      │262.84     │0 │262.62   │262.82      │
├───────┼───────┼──────┼─┼──────┼───────┼─
│263.33      │263.27      │263.23     │0 │264.22    │263.92     │
├───────┼───────┼──────┼─┼──────┼───────┼─
│1360000    │1150000    │300000   │0 │940000   │1040000    │
└───────┴───────┴──────┴─┴──────┴───────┴─

How would you amend (in place) the entire data (table) so that the box
at column 3, row 2, would have the literal value '262.73' instead of
zero?  This is the essence of what I was trying to ask.
