Check and correct table elements

You can view the table elements in the Tags panel and correct elements that are not correctly tagged with the Reading Order command.

1. Find the table tag <Table> in the Tags panel.
2. Check whether it is a correctly structured table which should meet either of the following structuring of table elements:

• Each Table Row contains Table Header <TH> or Table Data <TD> cells, or both.
• For <THead>, <TBody>, and <TFoot> sections, each of them contains Table Rows.

3. If the table’s rows, columns, and cells appear in the document, but the table tag doesn’t contain some of the elements mentioned above, tag the related element with the Reading Order command. Alternatively, re-create the table in the authoring application and then convert it to a tagged PDF.

To set ColSpan and RowSpan attributes for table elements, please do as the following:

1. Select a <TD> or <TH> element in the Tags panel. Click the Options menu at the top of the Tags panel and choose Properties…. (Or right-click a <TD> or <TH> element in the Tags panel and choose Properties… from the context menu.)
2. In the pop-up Object Properties dialog box, click Edit Attribute Objects in the Tag tab.
3. In the Attributes dialog box, select Attribute Objects and then click New Item to create a new Attribute Object dictionary.
4. Expand the created dictionary, select the Layout attribute, and click Change Item.
5. Change the Layout value to “Table” and click OK.
6. Then click the created dictionary and click New Item.
7. In the Add Key and Value dialog box, type “ColSpan” or “RowSpan” in the Key box, enter the number of columns or rows spanned in the Value box, choose Integer from the Value Type menu, and click OK.
