The attribute table is referenced when using this function even when it is not stored in the dataset, such as with raster datasets that contain internal attribute tables. When the dataset is displayed, it can be symbolized based on the table values. When a pixel is queried, the table values...
An attribute table may contain multiple fields with null values and by default, these fields are populated with an empty space. In some cases, some tools or functions do not execute if the fields are not populated with characters (non-nullable fields). 过程 The following are two possible meth...

Solved: I would like to open the attribute table for a selected layer. I was able to create table from a feature layer and have access to it. However, I do not know
arcpy.management.BuildRasterAttributeTable(in_raster, {overwrite}) 参数说明数据类型 in_raster 将向其添加表格的单波段栅格数据集。如果像素类型为浮点型或双精度,此工具则不会运行。 Raster Layer overwrite (可选) 指定是否要覆盖现有表。 NONE —现有的栅格属性表将不会被覆盖,所有编辑都将追加到当前表中。
For example, when the Pro attribute table pane is activated off a layer context menu, notice that the context of the associated active map view does not change: The currently active tab, tool, and TOC content have not changed because the attribute table pane is impersonating the active map....
