怎么精确控制solidworks里面的表格的位置

        public void SetTablePosition(TableAnnotation table, double x, double y)
        {
            table.Anchored = true;
            DrawingDoc swDrawing = (DrawingDoc)currentDoc;
            if (table.Anchored == true)
            {
                //Sheet sheet = v.Sheet;
                Sheet sheet = swDrawing.GetCurrentSheet() as Sheet;
                TableAnchor tableAnchor = sheet.get_TableAnchor((int)swTableAnnotationType_e.swTableAnnotation_General);
//Determine type of table anchor
                table.AnchorType = (int)swBOMConfigurationAnchorType_e.swBOMConfigurationAnchor_BottomLeft;

                // Set the new position of the table anchor
                double[] dNewPosition = new double[2];
                dNewPosition[0] = x;
                dNewPosition[1] = y;

                tableAnchor.Position = dNewPosition;
            }
            table.Anchored = false;
        }
