Class XSSFTable

java.lang.Object
  org.apache.poi.POIXMLDocumentPart
      org.apache.poi.xssf.usermodel.XSSFTable

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) This implementation works under the assumption that a table contains mappings to a subtree of an XML. The root element of this subtree an occur multiple times (one for each row of the table). The child nodes of the root element can be only attributes or element with maxOccurs=1 property set

XSSFTable

public XSSFTable()

empty implementation, not attached to a workbook/worksheet yet

XSSFTable

public XSSFTable(PackagePart part)
          throws java.io.IOException

Parameters:

part -

Throws:

java.io.IOException

Since:

POI 3.14-Beta1

readFrom

public void readFrom(java.io.InputStream is)
              throws java.io.IOException

read table XML

Parameters:

is -

Throws:

java.io.IOException

getXSSFSheet

public XSSFSheet getXSSFSheet()

Returns:

owning sheet

writeTo

public void writeTo(java.io.OutputStream out)
             throws java.io.IOException

write table XML to stream

Parameters:

out -

Throws:

java.io.IOException

commit

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

getCTTable

@Internal(since="POI 3.15 beta 3")
public org.openxmlformats.schemas.spreadsheetml.x2006.main.CTTable getCTTable()

get the underlying CTTable XML bean

Returns:

underlying OOXML object

mapsTo

public boolean mapsTo(long id)

Checks if this Table element contains even a single mapping to the map identified by id

Parameters:

id - the XSSFMap ID

Returns:

true if the Table element contain mappings

getCommonXpath

public java.lang.String getCommonXpath()

Calculates the xpath of the root element for the table. This will be the common part of all the mapping's xpaths Note: this function caches the result for performance. To flush the cache updateHeaders() must be called.

Returns:

the xpath of the table's root element

getXmlColumnPrs

public java.util.List<XSSFXmlColumnPr> getXmlColumnPrs()

Note this list is static - once read, it does not notice later changes to the underlying column structures To clear the cache, call updateHeaders()

Returns:

List of XSSFXmlColumnPr

addColumn

@Internal(value="Return type likely to change")
public void addColumn()

Adds another column to the table. Warning - Return type likely to change!

getName

public java.lang.String getName()

Specified by:

getName in interface Table

Returns:

the name of the Table, if set

setName

public void setName(java.lang.String newName)

Changes the name of the Table

Parameters:

newName -

getStyleName

public java.lang.String getStyleName()

Specified by:

getStyleName in interface Table

Returns:

the table style name, if set

Since:

3.17 beta 1

setStyleName

public void setStyleName(java.lang.String newStyleName)

Changes the name of the Table

Parameters:

newStyleName -

Since:

3.17 beta 1

getDisplayName

public java.lang.String getDisplayName()

Returns:

the display name of the Table, if set

setDisplayName

public void setDisplayName(java.lang.String name)

Changes the display name of the Table

Parameters:

name - to use

getNumberOfMappedColumns

public long getNumberOfMappedColumns()

Returns:

the number of mapped table columns (see Open Office XML Part 4: chapter 3.5.1.4)

getNumerOfMappedColumns

public long getNumerOfMappedColumns()

Deprecated. 3.15 beta 2. Use getNumberOfMappedColumns().

Returns:

the number of mapped table columns (see Open Office XML Part 4: chapter 3.5.1.4)

getCellReferences

public AreaReference getCellReferences()

Returns:

The reference for the cells 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().

Since:

3.17 beta 1

setCellReferences

public void setCellReferences(AreaReference refs)

Updates the reference for the cells of the table (see Open Office XML Part 4: chapter 3.5.1.2, attribute ref) and synchronizes any changes

Since:

3.17 beta 1

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, updateReferences() is inexpensive.

Since:

POI 3.15 beta 3

getRowCount

public int getRowCount()

Returns:

the total number of rows in the selection. (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().

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 updateHeaders(), 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

Since:

3.15 beta 2

getSheetName

public java.lang.String getSheetName()

Specified by:

getSheetName in interface Table

Since:

3.15 beta 2

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

Since:

3.15 beta 2

See Also:

getTotalsRowCount()

getTotalsRowCount

public int getTotalsRowCount()

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:

3.17 beta 1

getHeaderRowCount

public int getHeaderRowCount()

Specified by:

getHeaderRowCount in interface Table

Returns:

0 for no header rows, 1 for table headers shown. Values > 1 might be used by Excel for pivot tables?
