* default format will only be used when a Format cannot be created from the
|
||||
* cell's data format string.
|
||||
*
|
||||
* <p>
|
||||
* Note that by default formatted numeric values are trimmed.
|
||||
* Excel formats can contain spacers and padding and the default behavior is to strip them off.
|
||||
* </p>
|
||||
* <p>Example:</p>
|
||||
* <p>
|
||||
* Consider a numeric cell with a value <code>12.343</code> and format <code>"##.##_ "</code>.
|
||||
* The trailing underscore and space ("_ ") in the format adds a space to the end and Excel formats this cell as <code>"12.34 "</code>,
|
||||
* but <code>DataFormatter</code> trims the formatted value and returns <code>"12.34"</code>.
|
||||
* </p>
|
||||
* You can enable spaces by passing the <code>emulateCsv=true</code> flag in the <code>DateFormatter</code> cosntructor.
|
||||
* If set to true, then the output tries to conform to what you get when you take an xls or xlsx in Excel and Save As CSV file:
|
||||
* <ul>
|
||||
* <li>returned values are not trimmed</li>
|
||||
* <li>Invalid dates are formatted as 255 pound signs ("#")</li>
|
||||
* <li>simulate Excel's handling of a format string of all # when the value is 0.
|
||||
* Excel will output "", <code>DataFormatter</code> will output "0".
