The TableFrameElement class provides access to capabilities that allow you to modify how tabular information is displayed on the Layout class.
Discussion
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.
Propriétés
Propriété | Explication | Type de données |
anchor (Lecture seule) | Returns one of the following string values that represent the current anchor position. To change the value, use the setAnchor method.
| String |
elementHeight (Lecture et écriture) | The height of the element in page units. | Double |
elementPositionX (Lecture et écriture) | The x-location of the element's anchor position. The units assigned or reported are in page units. | Double |
elementPositionY (Lecture et écriture) | The y-location of the element's anchor position. The units assigned or reported are in page units. | Double |
elementWidth (Lecture et écriture) |
The width of the element in page units. | Double |
fields (Lecture et écriture) |
A list of strings that represent the table field names that are displayed in the table frame. | List |
locked (Lecture et écriture) | When set to True, the element cannot be graphically selected in the layout view. | Boolean |
longName (Lecture seule) | An element's full name including group information if it exists. For example, an element named 'Table Frame' in a group element named 'Group Element' will return a longName value of 'Group Element\\Table Frame'. If the element is not in a group, the longName will be the same as the name value. | String |
mapFrame (Lecture et écriture) | A reference to the associated MapFrame. | MapFrame |
name (Lecture et écriture) | The name of the element. It is important that all elements have a unique name so they can be uniquely referenced using the wildcard parameter with the listElements function on the Layout object. | String |
parentGroupElement (Lecture seule) | If the element is in a group, the value returned will be a GroupElement, otherwise a NoneType will be returned. | GroupElement |
query (Lecture seule) | Returns one of the following string values that represent the current query that controls which rows should be displayed.. To change the value, use the setQuery method.
| String |
table (Lecture et écriture) | Object | |
type (Lecture seule) | Returns a value of TABLEFRAME_ELEMENT. | String |
visible (Lecture et écriture) | Returns True if the element is visible on the layout. | Boolean |
Vue d’ensemble des méthodes
Méthode | Explication |
applyStyleItem (style_item) | Applies a StyleItem to a TableFrameElement. |
getDefinition (cim_version) | Returns a table frame element's CIM definition. |
setAnchor (anchor) | The setAnchor method controls the anchor position for a TableFrameElement value. |
setDefinition (definition_object) | The setDefinition method sets the CIM definition for a table frame element. |
setQuery (query_rows) | The setQuery method controls the display of rows in the table frame. |
sortFields (field_info) | The sortFields method sorts a table frame using a list of dictionary key-value pairs for one or many fields. |
Méthodes
applyStyleItem (style_item)
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.
Remarque :
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)
Paramètre | Explication | Type de données |
cim_version | A string that represents the major version of the CIM that will be used.
| String |
Type de données | Explication |
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)
Paramètre | Explication | Type de données |
anchor | A string that specifies the location of the anchor 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)
Paramètre | Explication | Type de données |
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)
Paramètre | Explication | Type de données |
query_rows | A keyword string that serves as a filter and specifies the rows that will be displayed in the table frame.
(La valeur par défaut est ALL_ROWS) | String |
sortFields (field_info)
Paramètre | Explication | Type de données |
field_info [field_info,...] | A list of Python dictionaries that each contain field sorting information. The dictionary keys are defined below.
| 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.
Exemple de code
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')
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)
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')
