I think that probably what you may be experiencing is a non uniform table.
As far as I am aware voiceover does not announce a non unified table layout
to alert you to this problem.
The non unified table layout will have varying columns and row  arrangements
throughout the table. Row one may have 3 columns and row 2 may have 6
columns for example.
So when coordinates are read outs as you move through the table this may
create a result which may not be easy to visualise without sight.
A solution may be to decrease Voiceover verbosity so that coordinates are
not read out which may make the table slightly more comprehensible.

Mac OS is generally pretty dreadful at handling tables but in this instance
Windows Screenreaders are little better though they will within documents
indicate if a table is non uniform. The solution generally on other
platforms is to copy the table off the web to a document format  in which
the table can be edited so that it becomes a regular uniform table . This is
impossible to achieve in Mac Os Word Processors but may be possible in a
Numbers  or tables Spreadsheet. As I never bother trying to handle tables
under Mac OS  I will have to defer to other people's experience here as to
whether this is a feasible work around. It is definitely a job which it is
useful to have sighted support for. I used to use my DSA support for these
sorts of problematic tables.

Unfortunately on all platforms,   I needed to use sighted support if I
wanted important table information..
