Hi Nguyen,
Thank you very much for using Syncfusion products.
We have created the sample at our side which contains the input template with Table and created the named range for the same table.
And inserting the rows at run time in the table named range , the rows are inserted correctly. We have placed the sample for your reference.
In the previous post specified that you are attached the input template, but we are unable to find the input template. Could you please upload the input file and the sample tried at your side so that we can sort out the actual cause of the issue.
Could you please let us know whether you are inserting rows at run time, and where you can set the autoinsertrows , Data source property for the table.
Please try the attached sample at your side and let us know if these helps you. Please revert back to us with the simplified sample if you have any concerns.
Please let us know if you require any further clarifications.
Thanks,
Sridhar.S
