- Method Detail
  - getSheets
```
List<? extends SheetDescriptor> getSheets()
```
    Get all sheet descriptors
  - getCells
```
Object[][] getCells(SheetDescriptor sheet)
```
    Parse and get all cells from a given sheet
    
    Parameters:
    
    sheet - sheet to parse
    
    Returns:
    
    parsed objects with types as in Excel
  - isUse1904Windowing
```
boolean isUse1904Windowing()
```
    Sometimes we need to convert parsed double value to date. For example a cell contains value 1.25, user sees it in Excel as 1.25 but in OpenL this value has a type Date. It should be converted from double to Date. (There is unit test for such case) We should get this property from workbook and use it in DateUtil.getJavaDate(double, boolean) to convert it correctly.
    
    Returns:
    
    The setting for a given workbook
  - getTableStyles
```
TableStyles getTableStyles(SheetDescriptor sheet,
                           IGridRegion tableRegion)
```
    Get styles for a given table
    
    Parameters:
    
    sheet - sheet containing the table
    
    tableRegion - region needed to get styles for a given table
    
    Returns:
    
    Cell styles
  - close
```

```
