PDF Tables are not tagged correctly: #1 Table Editor
1 of several problems in how PDF Maker (and InDesign's export to PDF utility) tag PDFs.
In Table Editor, the editor's cell markers (bright pink lines) do not align with the actual <TD> data cells. This makes it difficult, and sometimes impossible, to correct a cell's tag.
Most commonly seen in complex tables with merged cells in the column and row headers. See screen capture.

Table Editor's cell outlines should match the actual cells.
Can you please share a sample Office file with which issue is reproducible?
