Bug 131848

Description:
Summary : When I update a former report that was properly setup, I get extra columns.

Details: I start from a former release of a report, under ODF format and had to update it. The former report did show properly 25 columns. This report has : 1°) a page header, including a long label as report title with 25 labels as column headers underneath the long label, 2°) a detail section that contains the 25 fields.

I relocated the 22nd column in the 4th place and added-up a new one as 7th place. All labels have the same width and x-position as their related columns.

The result is not easily legible as there is an extra blank cell between the 6th and the 7th column and from then, every label is displayed in a two-cells fused cell. For the data fields, no extra cell between the 6th and the 7th column but every data is displayed in a two-cells fused cell. So the column header and the data are not aligned under each other and when I try to copy and paste the data in a neatly formatted sheet with conditional formatting, the data do not fit in the right place.

Thanks in advance for your help. Michel

Steps to Reproduce:
1.open a former report
2.move some columns header and some columns data fields to the right
3.add-up columns in the new created gap
4. move the moved columns back the left

Actual Results:
1. A new cell appear in the header row
2. The header cells at the right of this extra cell join 2 cells (no loss of header but header row width is almost doubled)
3. The data rows contain cells that join 2 cells (no loss of data but data rows width is almost doubled)
4. Data are aligned in their columns but not with their related headers (due to the extra cell described in 1.
5. Copy and paste to a display spreadsheet with nice formatting is almost impossible unless to be done one data column at a time.

Expected Results:
1. No extra cell in header row
2. Each header or data in a single cell in a compact table with no extra row.
