Hi Vin,
Greetings from Syncfusion support and sorry for the delay in providing the response.
Based on the query we would like to let you know that by default the Grid’s header text will be displayed based on the width set in the corresponding grid columns. This is the default behavior of html table. So when the column width is small the header text will shrink and display the three dots(…) for the text content accordingly.
So we suggest you to resolve this by either providing the required width for the Grid column(so that the header text is displayed fully) or use autoFitColumns method of the Grid which resizes the column to fit the widest cell’s content without wrapping.
More details on auto fit can be checked in the below documentation link,
Please get back to us if you require any further assistance.
Regards,
Sujith R
