i build document with table in loop with one object DocumentBuilder. like this
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.InsertCell();
builder.CellFormat.Shading.BackgroundPatternColor = rowColor;
builder.CellFormat.HorizontalMerge = CellMerge.First;
builder.CellFormat.BottomPadding = 5;
//builder.CellFormat.Width = 130;
builder.CellFormat.Width = tableWidth / aValues.Length;
builder.Write("text");
builder.EndRow();
how can i change font color in one cell, not all document?
