Using "BuiltinTableStyle" does not allow custom style ?!

[Testname]

Code snippet:
 
 table.ApplyStyle(BuiltinTableStyle.TableList3);
 
 //Does not work
 table[y , x].CellFormat.Borders.Top.BorderType = BorderStyle.None;
 //Does work.
table[y, zellenCounter].CellFormat.Borders.Top.LineWidth = 1.5f;

Hi Customer,

Thank you for contacting Syncfusion support.

On further analyzing with the given code snippet, you have used None border type which can used to avoid effect on border type. It gives No border to particular border type of Cell and value for it inherits from its parent.

If you want to clear any type of border for the particular cell, then you can use as “Cleared” from “BorderStyle” which used to set clear particular border.

Please find the below highlighted code snippet which illustrates the same. Please let us know if it helps you.
//Creates an instance of WordDocument Instance (Empty Word Document)
WordDocument wordDocument = new WordDocument();
//Adds a section into Word document
WSection wSection = wordDocument.AddSection() as WSection;
//Adds a new table into Word document
WTable wTable = wordDocument.LastSection.AddTable() as WTable;
//Specifies the total number of rows & columns
wTable.ResetCells(3, 3);
//Applies "TableList3" built-in style to table
wTable.ApplyStyle(BuiltinTableStyle.TableList3);

//Does not work case used with Cleared to work.
wTable[0, 0].CellFormat.Borders.Top.BorderType = BorderStyle.Cleared;

wTable[0, 1].CellFormat.Borders.Bottom.BorderType = BorderStyle.Cleared;
wTable[1, 1].CellFormat.Borders.Top.BorderType = BorderStyle.Cleared;

wTable[1, 2].CellFormat.Borders.Bottom.BorderType = BorderStyle.Cleared;
wTable[2, 2].CellFormat.Borders.Top.BorderType = BorderStyle.Cleared;
