Working with tables
Tables pose a special challenge for screen readers because they present textual or
numerical data to be easily referenced visually. Content within table cells can be complex
and might contain lists, paragraphs of text, form fields, or another table.
For best results when tagging tables, use the application that you created the document
with to add tags when you create the PDF document. (See Creating tagged Adobe PDF
from authoring applications.) If your PDF document isn't tagged, you can add tags by
using the Add Tags To Document command. Most tables are properly recognized using
this command; however, it may not recognize a table that lacks clear borders, headings,
columns, and rows. Use the TouchUp Reading Order tool to determine if the table has
been properly recognized and to correct recognition problems. (See
Checking highlighted
regions of figures and tables.) To add specialized formatting to tables and table cells, use
the Tags tab. (See
Using the Tags tab.)
To show table elements:
1. Select the TouchUp Reading Order tool, and then click Show Tables And Figures in the
dialog box.
2. Click Show Table Cells to verify that rows and columns in a table are correctly identified.
To tag unrecognized tables:
1. Select the TouchUp Reading Order tool, and then click Show Tables And Figures.
2. If the table isn't clearly labeled in the document pane, drag to select the entire table, and
then click Table in the dialog box.
3. Click Show Table Cells to make sure that all cells in the table are defined as individual
elements.
4. If cells don't appear as separate elements, do one of the following:
● If one or more cells are merged, use the TouchUp Reading Order tool to select the area
within a single cell, and then click Cell in the dialog box. Repeat for each merged cell.
● If cells aren't highlighted, the table may not use standard table formatting. Re-create the
table in the authoring application.
5. If the table contains cells that are intended to span across two or more columns, set
ColSpan and RowSpan attributes for these rows in the tag structure. (See Correcting tables
and table elements.)
