Please replace the below code in TableRdlGenerator.cs (line 110)

private Rdl.StyleType CreateHeaderTableCellTextboxStyle()
        {
            Rdl.StyleType headerTableCellTextboxStyle = new Rdl.StyleType();
            headerTableCellTextboxStyle.Items = new object[]
                {
                    "700",
                    "14pt"
                };
            headerTableCellTextboxStyle.ItemsElementName = new Rdl.ItemsChoiceType5[]
                {
                    Rdl.ItemsChoiceType5.FontWeight,
                    Rdl.ItemsChoiceType5.FontSize
                };
            return headerTableCellTextboxStyle;
        }

with

private Rdl.StyleType CreateHeaderTableCellTextboxStyle()
        {
            Rdl.StyleType headerTableCellTextboxStyle = new Rdl.StyleType();
            headerTableCellTextboxStyle.Items = new object[]
                {
                    "700",
                    "14pt",
                    Color.Black
                };
            headerTableCellTextboxStyle.ItemsElementName = new Rdl.ItemsChoiceType5[]
                {
                    Rdl.ItemsChoiceType5.FontWeight,
                    Rdl.ItemsChoiceType5.FontSize,
                    Rdl.ItemsChoiceType5.BackgroundColor,
                };
            return headerTableCellTextboxStyle;
        }
