• Click the top Menu bar. Go to View -> Show/Hide -> Side panels -> Accesibility tags

• A panel with a small tag icon will open on the left side of your screen showing your document's hidden structure tree.

Think of a PDF table as a set of nested boxes. Inside the Accessibility tags panel, click the + or arrow icons to expand the elements:

<Table>: The main box that holds the entire table.

<TBody> (Table Body): The inner section that groups all your table rows together.

<TR> (Table Row): Represents one horizontal row.

<TH> (Table Header): A special cell used for column or row titles.

<TD> (Table Data): A regular cell containing information, numbers, or text.

The easiest way to review and fix table headers and cell spans is through Adobe's visual Table Editor:

• On the right sidebar, click All Tools -> Prepare for Accessibility -> Fix reading order

A small Touch Up Reading Order pop-up menu box will open on your screen.

• Click the Table Editor button directly inside that pop-up menu box.

• Fix Header Cells:
  • Select the cells by dragging your mouse across them.
  • Right-click any selected cell -> select Table Cell Properties
  • Select Header Cells, then set the Scope to Column (for top headers) or Row (for side headers).
  • Click OK.

• Fix Data Cells:
  • If the cell is a standard text or numbers, select the cell, right-click -> Table Cell Properties.
  • Select Data Cell and click OK.
