1. Adobe InDesign 20.5
2. Flow the attached .txt files (tagged text) into an InDesign file. you'll need paragraph styles "TABC", "TABH1", "TABTX", and "TAB" (the paragraph for the table). You'll also need table style "TAB" and a cell style "tabtx".
3. The last cell in table 19.2 should be empty—no hard return. The the text in row 2, column 3 of table 19.4, "katab" should be italic.
4. There's a hard return in the last cell of table 19.2; any text in cell R2C3 in table 19.4 is not ital (but note that the text in table 19.2 at R2C3 is italic as expected.
5. See the attached tagged text and Word files as well as the attached screen shot.

When importing tagged text, I am seeing some formatting—like italic—dropped, and I'm also seeing extra hard returns inserted in the last cell of the table. These problems seem to be intermittent and unpredictable. For example, in a cell with this text

<CellStart:><ParaStyle:TAB_TX><cTypeface:Italic>katab<cTypeface:><CellEnd:>

"katab" is not being italicized, but in a cell with this text

<CellStart:><ParaStyle:TAB_TX><cTypeface:Italic>qəṭál<cTypeface:><CellEnd:>

"qəṭál" is italicized just fine.

If I copy and paste the "qəṭál" cell into the first file replacing the "katab" cell, "qəṭál" is not italicized. I've attached the tagged text and Word files for each.

The other weird thing I'm seeing is a hard return inserted in an otherwise empty last cell in the table. You can see it in the table 19.4 file.

If it helps, I can upload the InDesign template as well.
