We often want to export a table as an excel sheet. The system renders the
html and it seems like a waste of time to write it to the file system to
use the reader. This allows us to render the html and then just pass it to
a reader
Closes#1136
Calculation engine was resolving every function by first resolving its arguments
including IFs, this was causing significant over evaluation when IFs were used
as it meant for every case to be evaluated.
Introduce elements to identify ifs and enable better branch resolution
(pruning). We tag parsed tokens to associate a branch identifier to them.
Closes#844
Sheet titles containing " " or "!" will be quoted in formulas. This commit
fixes the lookup of sheets with this kind of title by trimming the quotes
during the lookup.
Without this any defined range referencing a sheet with " " or "!" in the title
name will be lost when reading the workbook from file.

`master` is now the only permanent branch. Features and fixes should be merged
into `master` when stable. Pull requests should be forked from `master`.
`develop` branch disappear entirely in favor of temporary features/fixes branches.
In case we generate Spreadsheet from html file and the code
in file have text color in css "color:#FF00FF" it will showing
as black color because it will render like rgb content with } "FF00FF}"
So, we fix it by adding missing bracket "{".
Closes#831
Using an operator is significantly faster than calling the max function.
As this method is called more than once per cell the difference adds up.
Closes#824
Removing the duplicate strtoupper call has a meaningful impact on
performance since this method is called at least once per cell.
`Worksheet::getCells` currently calls `strtoupper` twice. `strtoupper`
is kind of expensive and this method is called at least once for every
cell in the spreadsheet. By removing the unnecessary second call the
runtime decreases by 18% when importing a ~100K cell spreadsheet.
Closes#825
For large XLSX files `Reader/Xlsx::readColumnsAndRowsAttributes()` performs
a lot of calls to `$this->getReadFilter()` and `$this->getReadFilter()->readCell()`
as `readCell()` is called twice for each (possibbly filled) cell.
By ignoring calls to the DefaultReadFilter implementation (which always returns true),
using no custom read filter will not incur any runtime penalty.
The runtime penaltiy when using a custom read filter is reduced by a third by
caching the read filter into a variable instead of using the getter method.
Fixes issue #772.
Due to a limitation in Mpdf, the HTML string passed to its WriteHTML method
must not exceed a particular length. PhpSpreadsheet produces one HTML string
containing all spreadsheet data when writing to HTML, which can easily exceed
Mpdf's size limit. Thus, it was impossible to write large spreadsheets to PDF
using the Mpdf writer - this change fixes that issue.
Fixes#637Fixes#706
Commit 8dddf56 inadvertently removed the ability to omit the width
and height arguments to the OFFSET function. And #REF! is returned
because the function is validating that the new $pCell argument
is present. It is present, but it has been passed in the $height position.
We fixed this by always passing $pCell at the last position and filling
missing arguments with NULL values.
Fixes#561Fixes#565
When extracting sheet title from string reference (like `"Work!sheet1!A1"`), PHP function `explode()` divide this string into three parts: `['Work', 'sheet1', 'A1']`. And then these wrong values are used in formulas, ranges, etc.
This change fix that problem by using special function `Worksheet::extractSheetTitle()`. This function also has been changed to make sure that worksheet title can contain "!" character. So, that function search last position of "!" in reference string and divide it to 2 parts correctly: `['Work!sheet1', 'A1']`.
Fixes#325Fixes#662
When a formatting string has a locale in it an error can occur when outputting. For example when the format string with a locale such as `[$-1010409]#,##0.00;-#,##0.00` appears, a value of 9.98 comes back as $9.98. This is because at https://github.com/PHPOffice/PhpSpreadsheet/blob/1.4.0/src/PhpSpreadsheet/Style/NumberFormat.php#L711 the numberFormat regex will match to the zeros inside the locale ([$-1010409]). Attempts to adjust the numberFormat regex caused regressions in other tests. Adding another step to filter out the locale caused no regression.
Iterators prev() behavior is now consistent with next(), meaning
that it can go out of bounds and it must be validated with valid()
before using it.
Fixes#587Fixes#627
Rowspans/colspans are now respected for each HTML document added to an existing
spreadsheet as a new worksheet. The protected $rowspan class property should
be emptied on each call to `loadIntoExisting`.
Fixes#619Fixes#620
When cloning `BaseDrawing`, its worksheet will be set as null and thus be
orphaned. But when cloning the worksheet, it will re-assign itself as the
new worksheet for the BaseDrawing.
That way we avoid recursive cloning of a Worksheet that would clone a
BaseDrawing that would clone a Worksheet etc.

We now always trust the file extension to avoid false positive of mime
detection for most simple cases. But we still try to guess the mime type
if the file extension does not match or is missing.

Editing a Xlsx document using PhpSpreadsheet should preserve the workbook
view attributes of that document. For example, if the worksheet tabs are
hidden in the original document, they should remain hidden after updating.

Properly set the selected cells for worksheets with frozen panes when
writing Xlsx documents. Beforehand, the saved Xlsx documents were
generating corruption warnings when opened in Excel.

This change adds support for newer functions that are prefixed
by _xlfn. (#356). The calculation engine has been updated to
recognise these as functions, and drop the _xlfn. part.

Some computer programs will output xlsx files that do not compare 100%
to the standards. Excel will open the file without any problem.
setZoomScaleNormal() should throw exception when manually setting the
scale to less than or equals 0, but when reading files, we should
be able to read a file with such error, as Excel does.

CSV reader used to accept any file without any kind of check. That made

Column indexes are always based on 1 everywhere in PhpSpreadsheet.
This is consistent with rows starting at 1, as well as Excel
function `COLUMN()`. It should also make it easier to reason about
columns and rows and remove any doubts whether a specific method is
expecting 0 based or 1 based indexes.
