Created attachment 203255 [details] A worksheet with a table and a PivotTable exhibit the bug; as sen in LIbreOffie 3.1 To reproduce: 1. Open the attached document. 2. switch to sheet Pivot Table_Sheet1_1 3. Look at border on the table. 4. Click the 'button'-y control for the second column field (entitled "C"). 5. Consider how the border have changed. Expected Results: Some kind of coherent choice of which borders are drawn around what. Actual results: Weirdly, for a first-row value with a single second-row cell - no borders are drawn between the header column value cells, nor between columns; but for first-column value with several second-row cells - we get bounding-box borders and inter-line borders.
