All Implemented Interfaces:

Table
```
public class XSSFTable
extends POIXMLDocumentPart
implements Table
```
This class implements the Table Part (Open Office XML Part 4: chapter 3.5.1) Columns of this table may contains mappings to a subtree of an XML. The root element of this subtree can occur multiple times (one for each row of the table). The child nodes of the root element can be only attributes or elements with maxOccurs=1 property set.

protected void commit()
               throws java.io.IOException
```
    Description copied from class: POIXMLDocumentPart
    Save the content in the underlying package part. Default implementation is empty meaning that the package part is left unmodified.
    Sub-classes should override and add logic to marshal the "model" into Ooxml4J.
    For example, the code saving a generic XML entry may look as follows:
```
 protected void commit() throws IOException {
   PackagePart part = getPackagePart();
   OutputStream out = part.getOutputStream();
   XmlObject bean = getXmlBean(); //the "model" which holds changes in memory
   bean.save(out, DEFAULT_XML_OPTIONS);
   out.close();
 }
 
```
    Overrides:
    
    commit in class POIXMLDocumentPart
    
    Throws:
    
    java.io.IOException - a subclass may throw an IOException if the changes can't be committed

  - getCellReferences
```
public AreaReference getCellReferences()
```
    Get the area reference for the cells which this table covers. The area includes header rows and totals rows. Does not track updates to underlying changes to CTTable To synchronize with changes to the underlying CTTable, call updateReferences().
    
    Returns:

    Since:
    
    3.17 beta 1
    
    See Also:

```
public void setCellReferences(AreaReference refs)
```
    Set the area reference for the cells which this table covers. The area includes includes header rows and totals rows. Automatically synchronizes any changes by calling updateHeaders(). Note: The area's width should be identical to the amount of columns in the table or the table may be invalid. All header rows, totals rows and at least one data row must fit inside the area. Updating the area with this method does not create or remove any columns and does not change any cell values.
    
    Since:
    
    3.17 beta 1
    
    See Also:
    
    "Open Office XML Part 4: chapter 3.5.1.2, attribute ref"
  - setCellRef
```
@Internal
protected void setCellRef(AreaReference refs)
```
  - setArea
```
public void setArea(AreaReference tableArea)
```
    Set the area reference for the cells which this table covers. The area includes includes header rows and totals rows. Updating the area with this method will create new column as necessary to the right side of the table but will not modify any cell values.
    
    Parameters:
    
    tableArea - the new area of the table
    
    Throws:
    
    java.lang.IllegalArgumentException - if the area is null or not
    
    Since:
    
    4.0.0
  - getArea
```
public AreaReference getArea()
```
    Get the area that this table covers.
    
    Returns:
    
    the table's area or null if the area has not been initialized
    
    Since:
    
    4.0.0
  - getStartCellReference
```
public CellReference getStartCellReference()
```
    Returns:
    
    The reference for the cell in the top-left part of the table (see Open Office XML Part 4: chapter 3.5.1.2, attribute ref) Does not track updates to underlying changes to CTTable To synchronize with changes to the underlying CTTable, call updateReferences().
  - getEndCellReference
```
public CellReference getEndCellReference()
```
    Returns:
    
    The reference for the cell in the bottom-right part of the table (see Open Office XML Part 4: chapter 3.5.1.2, attribute ref) Does not track updates to underlying changes to CTTable To synchronize with changes to the underlying CTTable, call updateReferences().
  - updateReferences
```
public void updateReferences()
```
    Clears the cached values set by getStartCellReference() and getEndCellReference(). The next call to getStartCellReference() and getEndCellReference() will synchronize the cell references with the underlying CTTable. Thus this method is inexpensive.
    
    Since:
    
    POI 3.15 beta 3
  - getRowCount
```
public int getRowCount()
```
    Get the total number of rows in this table, including all header rows and all totals rows. (Note: in this version autofiltering is ignored) Returns 0 if the start or end cell references are not set. Does not track updates to underlying changes to CTTable To synchronize with changes to the underlying CTTable, call updateReferences().
    
    Returns:
    
    the total number of rows
  - getDataRowCount
```
public int getDataRowCount()
```
    Get the number of data rows in this table. This does not include any header rows or totals rows. Returns 0 if the start or end cell references are not set. Does not track updates to underlying changes to CTTable To synchronize with changes to the underlying CTTable, call updateReferences().
    
    Returns:
    
    the number of data rows
    
    Since:
    
    4.0.0
  - setDataRowCount
```
public void setDataRowCount(int newDataRowCount)
```
    Set the number of rows in the data area of the table. This does not affect any header rows or totals rows. If the new row count is less than the current row count, superfluous rows will be cleared. If the new row count is greater than the current row count, cells below the table will be overwritten by the table. To resize the table without overwriting cells, use setArea(AreaReference) instead.
    
    Parameters:
    
    newDataRowCount - new row count for the table
    
    Throws:
    
    java.lang.IllegalArgumentException - if the row count is less than 1
    
    Since:
    
    4.0.0
  - getColumnCount
```
public int getColumnCount()
```
    Get the total number of columns in this table.
    
    Returns:
    
    the column count
    
    Since:
    
    4.0.0
  - updateHeaders
```
public void updateHeaders()
```
    Synchronize table headers with cell values in the parent sheet. Headers must be in sync, otherwise Excel will display a "Found unreadable content" message on startup. If calling both updateReferences() and this method, updateReferences() should be called first. Note that a Table must have a header. To reproduce the equivalent of inserting a table in Excel without Headers, manually add cells with values of "Column1", "Column2" etc first.
  - findColumnIndex
```
public int findColumnIndex(java.lang.String columnHeader)
```
    Gets the relative column index of a column in this table having the header name column. The column index is relative to the left-most column in the table, 0-indexed. Returns -1 if column is not a header name in table. Column Header names are case-insensitive Note: this function caches column names for performance. To flush the cache (because columns have been moved or column headers have been changed), updateHeaders() must be called.
    
    Specified by:
    
    findColumnIndex in interface Table
    
    Parameters:
    
    columnHeader - the column header name to get the table column index of
    
    Returns:
    
    column index corresponding to columnHeader
    
    Since:

    Since:

  - isHasTotalsRow
```
public boolean isHasTotalsRow()
```
    Note: This is misleading. The Spec indicates this is true if the totals row has ever been shown, not whether or not it is currently displayed. Use getTotalsRowCount() > 0 to decide whether or not the totals row is visible.
    
    Specified by:
    
    isHasTotalsRow in interface Table
    
    Returns:
    
    true if a totals row has ever been shown for this table

```
    Specified by:
    
    getTotalsRowCount in interface Table
    
    Returns:
    
    0 for no totals rows, 1 for totals row shown. Values > 1 are not currently used by Excel up through 2016, and the OOXML spec doesn't define how they would be implemented.
    
    Since:

    Specified by:
