I found the below info in the JAWS help menu.
Tables in Word
JAWS detects when you move into, out of, and within a table (from row to row
or column to column) and even warns you when you TAB into the last cell.
also indicates when the number of columns changes from one row to another.
Table detection includes nested tables.
Press CTRL+INSERT+T to list all tables in the document. The list shows each
table and its dimensions. Select the table you want, and press ENTER to move
to it. The insertion point is placed in the first cell of the table, or in
the first form field in the table if the document is protected.
In Word, once in a table, press TAB to move to the next cell, and press
SHIFT+TAB to move to the prior cell. The JAWS standard commands for reading
are also supported. Refer to
Using JAWS to Navigate Tables.
To read a table row, press ALT+INSERT+R. To read a table column, press
Column and Row Titles
JAWS can be set to automatically announce the title of columns and/or rows
as you move through tables. To configure row and/or column title reading:
list of 4 items
1. Move to the column or row that contains the titles. If you are setting
both column and row titles, move to the cell where the column and row
the titles intersect.
2. Press INSERT+V to open the Adjust JAWS Verbosity dialog.
3. Move to Set Row Titles Column to specify row titles are within the
current column. Move to Set Column Titles Row to specify that column titles
the current row.
4. Press ENTER to close the dialog.
The Title Reading verbosity item is automatically set based on whether you
configured row titles, column titles, or both. If you feel you are receiving
too much information, return to the Adjust JAWS Verbosity dialog, move to
Title reading, and select the setting you want to use. The available
list of 4 items
. Read No Titles
. Read Column Titles
. Read Row Titles
. Read Both Titles
To reread a column title, press ALT+INSERT+SHIFT+C and to reread a row
title, press ALT+INSERT+SHIFT+R.
To reset the row and column title definitions to the default and turn off
title reading, open the Adjust JAWS Verbosity dialog, move to Clear Title
and press SPACEBAR.
Non Uniform Tables
Non uniform tables are tables with rows that span more than one column, or
columns that span more than one row. JAWS can provide detailed information
the table that can help you navigate and get oriented. If you do not want to
hear this information, press INSERT+V, select Table Description, and press
the SPACEBAR to choose Off. This setting is retained even after you quit
While Table Description is on, JAWS informs you when you move into a
non-uniform table. You can then press INSERT+F1 to learn more about the
table. If the
table contains merged columns, JAWS says, At least one cell in this table
spans more than one column. If the table contains merged rows, JAWS says,
least one cell in this table spans more than one row.
Tables with Merged Columns
If a table has merged cells that span one or more columns and Table
Description is on, JAWS announces when the number of columns changes as you
row to row with ALT+CTRL+UP or DOWN ARROW. For example, in a table with
eight columns, if you move from a regular cell to a cell that spans five
JAWS says, Number of columns changed from eight to four.
If you set a row to be used for column headers that contains a non uniform
number of cells, JAWS cannot properly associate the column headers. For
if you have a table with eight columns, but the first row contains only four
cells, and you assign that row for column headers, JAWS does not read the
column headers, but only states the position within the table.
If the first or last rows contain differing numbers of cells from the other
rows in a table, it may not be possible for JAWS to identify the top or
of a column. In this case, if you use the commands to move to the top or
bottom of a column, ALT+CTRL+SHIFT+UP ARROW and ALT+CTRL+SHIFT+DOWN ARROW,
announces that the move cannot be made, and the insertion point is not
Tables with Merged Rows
A table may have columns that span multiple rows. JAWS does not indicate
when you have moved from a regular cell into a cell that spans multiple
addition, you cannot use ALT+CTRL+UP or DOWN ARROW to navigate a table with
merged rows. If the table also has both merged rows and merged columns, you
may not be able to use ALT+CTRL+RIGHT or LEFT ARROW to navigate the table
either. Instead, use TAB and SHIFT+TAB to move through the table cells.
Creating Accessible Tables
You can create accessible tables for JAWS 6.0 or later solely by using
functionality available in Microsoft Word. This means that even those who do
use JAWS can mark table row and/or column headings for
