TableFrameElement—ArcGIS Pro

Zusammenfassung

The TableFrameElement class provides access to capabilities that allow you to modify how tabular information is displayed on the Layout class.

Diskussion

A table frame element is a specialized map surround that has an associated MapFrame element and is also dynamically linked to a Layer or Table object to display its rows and fields. The listElements method on the Layout class returns a Python list of all possible layout elements. To return a list of only TableFrameElement objects, use the TABLEFRAME_ELEMENT constant for the element_type parameter. A wildcard value can also be used to further refine the search based on the element name value. It is important to uniquely name each layout element so it can be referenced using ArcPy scripting.

All the parameters that are available to the createTableFrameElement method of the Layout class are also exposed on theTableFrameElement class—such as mapframe, table, and fields—making changes to existing table frames possible. There are a number properties you can use to resize and position a table frame. You can also modify the appearance of a table frame using the sortFields method or control the rows that appear in the table using the setQuery method. Table frame elements also have getDefinition and setDefinition methods you can use to modify additional properties that are not exposed to the TableFrameElement class. Refer to the examples below and the Python CIM access help topic for more information.

Methoden

applyStyleItem (style_item)

Parameter	Erläuterung	Datentyp
style_item	A reference to a StyleItem in a project.	StyleItem

When referencing a StyleItem using the listStyleItems method on the ArcGISProject class, the style_class parameter must be TABLE_FRAME. For more information and code samples, refer the to StyleItem help topic.

Hinweis:

Styles must be added to a project prior to using the applyStyleItem method. They can be added using the updateStyles method on the ArcGISProject class.

getDefinition (cim_version)

Parameter	Erläuterung	Datentyp
cim_version	A string that represents the major version of the CIM that will be used. V2—The 2.x version of the CIM will be used. V3—The 3.x version of the CIM will be used.	String

Rückgabewert

Datentyp	Erläuterung
Object	Returns the CIM definition for a TableFrameElement value.

For more information about working with the CIM and samples, see Python CIM access.

setAnchor (anchor)

Parameter	Erläuterung	Datentyp
anchor	A string that specifies the location of the anchor position. BOTTOM_LEFT_CORNER—The anchor will be set at the bottom left corner position. BOTTOM_MID_POINT—The anchor will be set at the bottom center position. BOTTOM_RIGHT_CORNER—The anchor will be set at the bottom right corner position. CENTER_POINT—The anchor will be set at the center position. LEFT_MID_POINT—The anchor will be set at the left center position. RIGHT_MID_POINT—The anchor will be set at the right center position. TOP_LEFT_CORNER—The anchor will be set at the top left corner position. TOP_MID_POINT—The anchor will be set at the top center position. TOP_RIGHT_CORNER—The anchor will be set at the top right corner position.	String

Setting the anchor position is helpful because you can control how the element might expand when resized. For example, the default anchor position for a table frame element is TOP_LEFT_CORNER. If you change the anchor location to BOTTOM_RIGHT_CORNER, changing elementHeight will expand the element upward instead of downward (the default), and changing elementWidth will expand the element to the left.

setDefinition (definition_object)

Parameter	Erläuterung	Datentyp
definition_object	A modified CIM definition object originally retrieved using getDefinition.	Object

For more information about working with the CIM and samples, see Python CIM access.

setQuery (query_rows)

Parameter	Erläuterung	Datentyp
query_rows	A keyword string that serves as a filter and specifies the rows that will be displayed in the table frame. ALL_ROWS—All rows in the table will be displayed. MAPSERIES_ROWS—The row associated with the current index feature will be displayed if a spatial map series is enabled. VISIBLE_ROWS—Only the visible features in the map frame will be displayed. (Der Standardwert ist ALL_ROWS)	String

Parameter

Erläuterung

Datentyp

query_rows

A keyword string that serves as a filter and specifies the rows that will be displayed in the table frame.

ALL_ROWS—All rows in the table will be displayed.
MAPSERIES_ROWS—The row associated with the current index feature will be displayed if a spatial map series is enabled.
VISIBLE_ROWS—Only the visible features in the map frame will be displayed.

(Der Standardwert ist ALL_ROWS)

String

The default value is ALL_ROWS when creating a table frame. If you use the MAPSERIES_ROWS value, ensure that the Layout object has a spatial MapSeries value enabled; otherwise, you may not get the expected results.

sortFields (field_info)

Parameter	Erläuterung	Datentyp
field_info [field_info,...]	A list of Python dictionaries that each contain field sorting information. The dictionary keys are defined below. name—A string that represents the name of the field used to sort. ascending—A Boolean value of True will sort in ascending order. The default value is True. caseSensitive—A Boolean value of True will honor case while sorting. The default value is True.	List

Sorting applies to all fields at once and is based on the order of the fields defined in the field_info list. You must re-create all the sorting information for all the relevant fields and pass that information into the field_info parameter.

Codebeispiel

TableFrameElement example 1

The following script creates a table frame in a layout. Its uses a function to construct the envelop used to place the table frame on the layout.

def MakeRec_UL(ulx, uly, w, h):
    xyRecList = [[ulx, uly], [ulx+w, uly], [ulx+w,uly-h], [ulx,uly-h], [ulx,uly]]
    array = arcpy.Array([arcpy.Point(*coords) for coords in xyRecList])
    rect = arcpy.Polygon(array)
    return rect

p = arcpy.mp.ArcGISProject('current')
m = p.listMaps('Map')[0]
lyr = m.listLayers('States*')[0]
lyt = p.listLayouts('Create*')[0]
mf = lyt.listElements()[0]

#States table frame
tfStyle = p.listStyleItems('ArcGIS 2D', 'TABLE_FRAME', 'Blue Alternating Rows')[0]
tfEnv = MakeRec_UL(0.5, 5, 7.5, 4)
tfFields = ['STATE_NAME', 'STATE_ABBR', 'POP2000', 'POP2010']
tf = lyt.createTableFrameElement(tfEnv, mf, lyr, tfFields, tfStyle, 'States TableFrame')

#Display only visible rows
tf.setQuery('VISIBLE_ROWS')

TableFrameElement example 2

The following script references an existing table frame and uses class methods to modify its appearance. The script makes additional changes to properties that are exposed via Python CIM access.

p = arcpy.mp.ArcGISProject('current')
lyt = p.listLayouts('Modify*')[0]
tf = lyt.listElements('TABLEFRAME_ELEMENT', 'States*')[0]

#Modify table frame
tf.setQuery('VISIBLE_ROWS')
tf.sort({'name':'STATE_NAME', 'ascending':True, 'caseSensitive':True})

#Modify additional properties using the CIM
tf_cim = tf.getDefinition('V3')
tf_cim.minFontSize = 8
tf_cim.alternate1RowBackgroundCount = 2
tf_cim.alternate2RowBackgroundCount = 2
tf_cim.balanceColumns = False
tf_cim.columnGap = 75
tf_cim.fittingStrategy = 'AdjustColumnsAndSize'
tf.setDefinition(tf_cim)

TableFrameElement example 3

The following script creates a spatial map series prior to creating a new table frame. It finishes by setting the query value to MAPSERIES_ROWS.

def MakeRec_UL(ulx, uly, w, h):
    xyRecList = [[ulx, uly], [ulx+w, uly], [ulx+w,uly-h], [ulx,uly-h], [ulx,uly]]
    array = arcpy.Array([arcpy.Point(*coords) for coords in xyRecList])
    rect = arcpy.Polygon(array)
    return rect

p = arcpy.mp.ArcGISProject('current')
m = p.listMaps('Map')[0]
lyr = m.listLayers('GreatLakes')[0]
lyt = p.listLayouts('MapSeries')[0]
mf = lyt.listElements()[0]

#Create a spatial map series
lyt.createSpatialMapSeries(mf, lyr, 'NAME', 'AREA')

#Create a table frame
tfStyle = p.listStyleItems('ArcGIS 2D', 'TABLE_FRAME', 'Orange Alternating Rows')[0]
tfEnv = MakeRec_UL(0.5, 5.75, 7.5, 2)
tf = lyt.createTableFrameElement(tfEnv, mf, lyr, ['NAME', 'AREA'], tfStyle, 'Great Lakes TableFrame')

#Set the query to match mapseries rows
tf.setQuery('MAPSERIES_ROWS')
