Hello I am currently using the version of SyncfusionXlsIO.Net.Core and I've got an issue with the apply marker when I have a column Image (byte[]) inside my DataTable.

DataColumn.DataType = typeof(byte[]);

DataRow['Image'] = File.ReadAllBytes(path)

When my table has more than 1 image it works perfectly (the applymarker inserts the images), but when the DataTable contains only one row, it write in the cell : System.Byte[]

I dont understand why it works for more than one row only.

Than you,

Hi Betbeder, 

Greetings from Syncfusion. 

We are unable to reproduce the reported issue while applying Template Markers. The sample which we have tried at our end can be downloaded from the following link. 

Kindly modify the sample and share us the issue reproducing one, which will be helpful for us to investigate further and provide prompt solution at the earliest.
