Fix#3951. When an Excel sheet is protected, even when sorting is explicitly allowed without a password, sorts are permitted only on "protected ranges" within the sheet. PhpSpreadsheet already supports protected ranges, and only minor tinkering is necessary for that (e.g. the protected range can have, but does not require, a password). The more important part of this change is documenting the far-from-intuitive way that Excel handles this. To that end, documentation is updated, and a new sample is added.
A new class, `Worksheet\ProtectedRange` is added in place of the string array which had been used. `Worksheet::getProtectedCells` is deprecated in favor of the new `Worksheet::getProtectedCellRanges`.
Tcpdf issues warnings when processing hidden rows. Some time ago, Mpdf was having problems in the same situation; this was resolved by not writing out hidden rows in the html which Mpdf uses to generate its file. The same solution can be easily applied to Tcpdf.
Neither Tcpdf nor Mpdf handles hidden columns. Dompdf doesn't have a problem with either rows or columns. At any rate, the solution for Tcpdf/Mpdf is to not write out the data in the hidden columns. It is more difficult to implement this for columns than for rows, but this PR should do the trick.
Html writer generally uses `display:none` for the data in suppressed columns. This works, but is technically incorrect - the "approved" method is `visibility:collapse` on the col element. However, Firefox doesn't handle that correctly (open bug was filed over a decade ago), and, since all browsers seem to handle the existing implementation, it is left alone.
Among other considerations, this PR is a necessary precursor for supporting printArea in Html/Pdf should we decide to do that (issue #3941).
Writer/Html protected property `$isMPdf` is deprecated with this PR in favor of testing for `instanceof Mpdf`.
Fix#3935. Xls Reader cannot parse user's spreadsheet, failing on a token of 3d. I believe that, according to https://msopenspecs.azureedge.net/files/MS-XLS/%5bMS-XLS%5d.pdf, this represents a PtgAreaErr3d, i.e. an invalid reference. User cannot provide spreadsheet, but was quite forthcoming in providing additional debugging information. I am usually reluctant to make changes without a test case, however, in this case, the action being taken (treat "builtin" defined name as "not builtin" when it cannot be parsed) makes sense, and it satisfies the user's processing.
Fix#3923. Cells which have not yet been allocated cause problems when they need to be moved due to a column/row insert/delete. Code had been added in ReferenceHelper earlier to create missing cells, but only in the last data column. It needs to change to create the missing cells:
- for columns, in rows 1 to "highest data row" for columns "before column" to "highest data column".
- for rows, in columns A to "highest data column" for rows "before row" to "highest data row".
Excel supports the following notations for cell styles:
- `[$-F800]` and `[$-x-sysdate]` will format the date according to what appears to be the user's system long date format.
- `[$-F400]` and `[$-x-systime]`, will format the time according to what appears to be the user's system long time format.
- Builtin style 14 will format date according to what appears to be the user's system short date format.
- Builtin style 22 will format date and time according to the user's preference. It appears that the date portion is formatted according to the user's system short date format, but the time portion is formatted according to a format which is neither system short time format nor system long time format, so I'm not sure how this preference is set.
For F800, sysdate, F400, and systime, any other characters in the style are ignored, except that, if you have more than one of this type of block in the style, Excel will treat it as corrupt (error message on open and style changed to General).
Support is added for the new codes. In addition, note that the value displayed in the cell may differ in different environments. To give the PhpSpreadsheet programmer an opportunity to emulate what the intended audience will most often see, properties `shortDateFormat` (default value is builtin 14), `longDateFormat` (default value is `dddd, mmmm d, yyyy`), `dateTimeFormat` (defaults to builtin 22), and `timeFormat` (default is `FORMAT_DATE_TIME2`), with corresponding setters and getters, are added to Style/NumberFormat. Note that, if these properties are set to some other value in PhpSpreadsheet, it will not affect the values in the cell or the style - it is merely a convenience for the programmer. It will, however, affect column width if autosize is specified for the column. If the programmer does not alter any of the new properties, the output should be unchanged from before for builtins 14 and 22.
The new styles are also recognized by the `TEXT` function. In this case, the cell's calculated value may differ from user to user.
Note that this is a small subset of adding locale information to styles. No attempt is made to support any of the other possibilities - locale data will continue to be passed through to the spreadsheet, but PhpSpreadsheet will discard it before attempting to generate the formatted value of a cell.
It pointed out a problem that I would have thought should result in test failure. Code corrected, and documentation updated to describe the unexpected behavior.
Fix#3918, sort of. Xlsx cells use the default style when they omit the `s` tag, or when `s="0"` is specified. LibreOffice does not honor Alignment in the default Style unless the cell explicitly uses the second form, even though it honors other default Styles (e.g. bold font) when `s` is omitted. Gnumeric seems to have the same problem. A bug report has been filed with LibreOffice.
In the meantime, this PR adds to Xlsx Writer an optional boolean property `explicitStyle0` with setter and getter. Default is false, which will continue the current behavior by adding an `s` tag only when the cell uses a non-default style (this is how Excel itself behaves). When set to true, Xlsx Writer will explicity write `s="0"` for all cells using default style. This will allow users to create an Xlsx spreadsheet with default alignment of cells that will show up correctly when the spreadsheet is viewed with LibreOffice. Technically speaking, it is *probably* safe to always use `true`, except that the spreadsheet size will be a bit larger. However, my hope is that this is a temporary measure which can go away when the vendors have had a chance to fix their problems, hence the `false` default.
Fix#3730. File workbook.xml.rels in test file specified absolute addressing for shared strings, styles, and worksheets. Previous changes had addressed absolute addressing for worksheets, but shared strings and styles had not yet been addressed.
Before it was a bug when flooring negative numbers added to the length of
the number for the sprintf mask.
For example -0.091 becomes -9.1 in percentage, floors to -10 which is going to
increase $wholePartSize by 1 and add a leading zero to the result: -09.1% with
format 0.0%.
This happened for negative ranges where floor will increse the length of
the original number.
Fix#3909. SUMPRODUCT is mishandling multi-row ranges. In Calculation/Calculation, `checkMatrixOperands` will often resize its operands. When it does so, it needs to recalculate the dimensions of each. This fixes the reported problem.
Likely cause was PR #3260. That ticket noted the poor coverage of the code being replaced. Tests of the problem in this ticket were absent and are now added. Despite this, I note that `resizeMatricesShrink` is virtually uncovered, and `resizeMatricesExpand` has substantial gaps in its coverage. I have covered some, but not all, of the Expand gaps. I am struggling to come up with examples to fill its remaining gaps and those for Shrink. However, I will merge this fix in about a week even if I don't succeed.
Fix#3907. After row/column insertion/deletion, PhpSpreadsheet updates formulas which include cells which have moved. However, it can mis-identify cell addresses within the formula. Examples:
- `=SUM(A2,'F1 (SETTINGS)'!A1:B1)` It identifes F1 as a cell address.
- `=SUM(A2,'x F1 (SETTINGS)'!A1:B1)` It identifes F1 as a cell address. (This looks the same as the above, but, for technical reasons, it's different.)
- `=SUM(A2,definedname1A1)` It identifes A1 as a cell address.
- Sheet names in formulas are compared case-sensitively, and should be compared insensitively. This can make a difference if the formula includes its own sheet name, e.g. on sheet `Data`, formula `=SUM(DATA!A1:A2)` might have to change, but it will not do so with the existing logic.
The defined name part is fairly straightforward. The regular expressions that identify a cell address just have to be a bit more robust. It was doing a negative look-behind for an alphabetic character or dollar sign; underscore, period, and digits, all of which can be part of a defined name, need to be added to that list.
The other situations need a bit of a kludge, but not one so bad that I'm ashamed of it. The formulas will be altered before analysis so that sheet names are replaced with Unicode FFFD (sheetname does not match current sheet), FFFC (sheetname, enclosed in apostrophes, matches current sheet), and FFFB (sheetname, not enclosed in apostrophes, matches current sheet). This prevents the existing regular expressions from finding a cell address within a sheet name, and makes it easy to restore the original, with or without apostrophes, when the sheet name matches the current sheet and the cell(s) which it qualifies have to be changed.
Tests are added for all the situations mentioned above. No existing tests required changes.
