The way i used to convert ur DesignLink table into normal AutoCAD table with lines and (m)texts.
1: without loading DesignLink, the DesignLink table will be shown by ACAD_PROXY_OBJECT
2: Explode the Proxy table
3: Move the new created objects to another position out the source table as u can not edit the source proxy table.
4: Convert the 3DFACEs used as the border line of new creaded table into lines. I recommend these steps becoz no program is needed:
4.1: Change all table contents to a new individual layer and turn it off
4.2: Run WMFOUT and select the left 3DFACEs
4.3: WMFIN the WMF file with scale=2
4.4: Move the WMFIN empty table to the same position of the 3DFACE table
4.5: Erase all 3DFACEs in table
5: Explode the WMFIN table, turn on the content layer and then u will have a normal AutoCAD drawn table
That is not the native ACAD_TABLE, it is a drawn table and when u have it, you can then choose a software to convert the drawn table into Excel.
