How to update the data in ACAD_TABLE please?

[mozman]

The ACAD_TABLE entity is just preserved, you can not edit or query the content.

Do you know if the query of the ACAD_TABLE entity content will be supported in future releases?

[mozman]

Yes, I can answer that:

No, the ACAD_TABLE object is far too complicated and not documented enough to implement. I know that from my experiences with the MLEADER object.

Thanks for the reply. Do you know if, as an alternative, Excel tables inserted as OLE objects can be read?

[mozman]

No, OLE and OL2 entities are also just preserved.

You have access to the DXFTagStorge entity which stores the tags of unsupported entities:

This script reads the cell values from a simple table:

import ezdxf

def main():
    doc = ezdxf.readfile(r"C:\Source\ezdxf.git\examples_dxf\acad_table_simple.dxf")
    msp = doc.modelspace()
    table = msp.query("ACAD_TABLE").first
    acdb_table = table.xtags.get_subclass("AcDbTable")
    values = [tag.value for tag in acdb_table.find_all(302)]
    print("Table Values:")
    print(values)


if __name__ == "__main__":
    main()

output:

Table Values:
['Title', '', '', '1', '2', '3', '4', '5', '6']

Here is the DXF reference of ACAD_TABLE - have fun!

[mozman]

I added a helper function to ezdxf for that task:

import ezdxf
from ezdxf.entities.acad_table import read_acad_table_content


def main():
    doc = ezdxf.readfile(r"C:\Source\ezdxf.git\examples_dxf\acad_table_simple.dxf")
    msp = doc.modelspace()
    table = msp.query("ACAD_TABLE").first
    values = read_acad_table_content(table)
    print("Table Values:")
    print(values)

if __name__ == "__main__":
    main()

output as list of rows:

Table Values:
[['Title', '', ''], ['1', '2', '3'], ['4', '5', '6']]

Thanks for the answer, I was able to read the values ​​of the cells of the acad_table entity. Now it's time to play with them
