    row - representing a row to remove.
  - getRow
```
public HSSFRow getRow(int rowIndex)

    Specified by:
    
    setColumnHidden in interface Sheet
    
    Parameters:
    
    columnIndex - - the column to get (0-based)
    
    hidden - - the visiblity state of the column
  - isColumnHidden
```
public boolean isColumnHidden(int columnIndex)
```
    Get the hidden state for a given column.
    
    Specified by:
    
    isColumnHidden in interface Sheet
    
    Parameters:
    
    columnIndex - - the column to set (0-based)
    
    Returns:
    
    hidden - false if the column is visible
  - setColumnWidth
```
public void setColumnWidth(int columnIndex,
                           int width)
```
    Set the width (in units of 1/256th of a character width)
    The maximum column width for an individual cell is 255 characters. This value represents the number of characters that can be displayed in a cell that is formatted with the standard font (first font in the workbook).
    Character width is defined as the maximum digit width of the numbers 0, 1, 2, ... 9 as rendered using the default font (first font in the workbook).
    Unless you are using a very special font, the default character is '0' (zero), this is true for Arial (default font font in HSSF) and Calibri (default font in XSSF)
    Please note, that the width set by this method includes 4 pixels of margin padding (two on each side), plus 1 pixel padding for the gridlines (Section 3.3.1.12 of the OOXML spec). This results is a slightly less value of visible characters than passed to this method (approx. 1/2 of a character).
    To compute the actual number of visible characters, Excel uses the following formula (Section 3.3.1.12 of the OOXML spec):
    width = Truncate([{Number of Visible Characters} * {Maximum Digit Width} + {5 pixel padding}]/{Maximum Digit Width}*256)/256
    Using the Calibri font as an example, the maximum digit width of 11 point font size is 7 pixels (at 96 dpi). If you set a column width to be eight characters wide, e.g. setColumnWidth(columnIndex, 8*256), then the actual value of visible characters (the value shown in Excel) is derived from the following equation: Truncate([numChars*7+5]/7*256)/256 = 8;
    which gives 7.29.
    
    Specified by:
    
    setColumnWidth in interface Sheet
    
    Parameters:
    
    columnIndex - - the column to set (0-based)
    
    width - - the width in units of 1/256th of a character width

  - addMergedRegionUnsafe
```
public int addMergedRegionUnsafe(CellRangeAddress region)
```
    Adds a merged region of cells (hence those cells form one). Skips validation. It is possible to create overlapping merged regions or create a merged region that intersects a multi-cell array formula with this formula, which may result in a corrupt workbook. To check for merged regions overlapping array formulas or other merged regions after addMergedRegionUnsafe has been called, call validateMergedRegions(), which runs in O(n^2) time.
    
    Specified by:
    
    addMergedRegionUnsafe in interface Sheet
    
    Parameters:
    
    region - to merge
    
    Returns:
    
    index of this region
    
    Throws:
    
    java.lang.IllegalArgumentException - if region contains fewer than 2 cells
  - validateMergedRegions
```
public void validateMergedRegions()
```
    Verify that merged regions do not intersect multi-cell array formulas and no merged regions intersect another merged region in this sheet.
    
    Specified by:
    
    validateMergedRegions in interface Sheet
    
    Throws:
    
    java.lang.IllegalStateException - if region intersects with a multi-cell array formula
    
    java.lang.IllegalStateException - if at least one region intersects with another merged region in this sheet
  - setForceFormulaRecalculation
```
public void setForceFormulaRecalculation(boolean value)
```
    Control if Excel should be asked to recalculate all formulas on this sheet when the workbook is opened.
    Calculating the formula values with FormulaEvaluator is the recommended solution, but this may be used for certain cases where evaluation in POI is not possible.
    It is recommended to force recalcuation of formulas on workbook level using Workbook.setForceFormulaRecalculation(boolean) to ensure that all cross-worksheet formuals and external dependencies are updated.
    
    Specified by:
    
    setForceFormulaRecalculation in interface Sheet

    Returns:
    
    true if an uncalced record must be inserted or not at generation
