Is it possible to hide or delete an existing table from Word document, if some condition is true (DataTable is empty for example)

DataTable mDataTable = GetTestOrder(ID);

if (mDataTable.Rows.Count == 0)
    REMOVE / DELETE / HIDE Table???
else
    doc.MailMerge.ExecuteGroup(mDataTable);

Hi Silvester,

Thank you for your interest in Syncfusion products.

To remove an existing table from word document, you can simply call below code snippet.

Code snippet:

//Get Table object

IWTable table = document.Section[0].Tables[0];

//Remove table if DataTable is empty

if (mDataTable.Rows.Count == 0)

        //Remove Table object from the child entity collection of first section’s textbody

        document.Section[0].Body.ChildEntities.Remove(table);

//Alternatively you can directly remove the table from child entity collection by providing index (location) in owner collection

document.Section[0].Body.ChildEntities.RemoveAt(0);

We have prepared a simple sample to illustrate this usage in below link. 
Sample Link:
GenerateWord.zip

If you are using mail merge with Groups in your application, there is an alternate solution by simply setting RemoveEmptyGroup property of MailMerge class to true and place the table in the input template within Begin and End Group fields, DocIO will handle the logic of removing empty groups (elements between Begin and End Group) when the data table is empty.

Code snippet:

//Removes Empty Group during Mailmerge           

document.MailMerge.RemoveEmptyGroup = true;

We have prepared a simple sample to illustrate this usage in below link. 
Sample Link:
GenerateWord_MailMerge.zip

kindly try running the above samples and let us know if this helps you.

Thanks a lot

We try the function RemoveEmptyGroup in this sample but it doesn't wotk like we want.
The sample :
"BeginGroup:Test"
The text "Fusion"
"EndGroup:Test"
We would nothing in the file when there is no "Test" (ie Test = null).
But we obtain :
The text

Thanks.
