Uncaught TypeError: Cannot read property 'length' of undefined

This error occurs after I have loaded a word document (.docx) using the supplied .Net Core example code from the backend server and am displaying in a DocumentEditorContainer. 

While editing the document, when I try to delete a table row this error is thrown and the table row is not deleted visually. However the row IS deleted after I click off of a table object in the document editor. After doing this, the rows are deleted (or the layout is recalculated).

Using:

  • Vue.js 2.6.11
  • .Net Core 3.1. 
  • SyncFusion ej2-vue-documenteditor 19.2.56.
  • Chrome  92.0.4515.159 64-bit

Hi DT, 
 
Syncfusion Greetings! 
 
We tried to reproduce the reported issue but couldn’t. We suspect that the reported problems are might be due to the table in the input word document which used at your end. We need to investigate with the contents in your input Word document to reproduce the exact problem at our end. So, could you please provide us the input Word document which used at your end. Thereby, we will analyze further and provide you the appropriate solution at the earliest. 
  
Note: If you have any confidential data in your Word document, please replace with some dummy data and provide us the same. We just need your document to recreate the problem you face. 
 
Regards, 
Suriya M.

Thank you for the response. I have attached a sample word doc which should reproduce the error. Please let me know if you need additional info on this, or if a short clip would help.


Thank you.

Further to my last response, is there a particular way the table should be formatted in a .docx to best transfer to SyncFusion's DocumentEditor. I appear to have mixed results with table spacing in different .docx files.

For example, the previously attached sample doc (above) renders the table with the same row/cell vertical spacing as in the original Word doc. However in a different Word doc, all the tables in it seem to have their vertical row/cell spacing doubled (example below).

Neither table in the different documents have any special formatting so far as I can tell.

Original:

Rendered:


The above demonstrated sizing difference occurs throughout the entire document, this is just a snip.

I understand about SF's pagination and the difference between Word's sizing vs HTML, but since this occurs in different documents, it would seem to be something about the documents themselves rather than SyncFusion.


Thank you.

DT Doug Thierjung replied to Kurthis Banu Abdul Majeeth August 30, 2021 02:25 PM UTC

Regarding the table spacing issue, would you be able to say what constitutes a table style? Are the changing of the borders, row spacing, column width, etc all considered table style with respects to SyncFusion's current support of it?


Thank you.


KB Kurthis Banu Abdul Majeeth Syncfusion Team August 31, 2021 09:55 AM UTC

Hi DT, 
 
Regarding: To remove the table style 

1.       Click anywhere on the table, then click the Table Design tab on the right side of the Ribbon. 
2.       Locate the Table Styles group, then click the More drop-down arrow to see all available table styles. 
3.       And then click “Clear” option to remove the table style and resave the document. 

For your better understanding we had attached video demonstration in below link.
