为什么试图在数据透视表中着色范围没有效果（Aspose Cells）？

我试图有条件地着色数据透视表中的范围，如下所示：

private void ColorizeContractItemBlocks(List<string> contractItemDescs) { int FIRST_DESCRIPTION_ROW = 7; int DESCRIPTION_COL = 0; int ROWS_BETWEEN_DESCRIPTIONS = 4; var pivot = pivotTableSheet.PivotTables[0]; var dataBodyRange = pivot.DataBodyRange; int currentRowBeingExamined = FIRST_DESCRIPTION_ROW; int rowsUsed = dataBodyRange.EndRow; pivot.RefreshData(); pivot.CalculateData(); // Loop through PivotTable data, colorizing contract items while (currentRowBeingExamined < rowsUsed) { Cell descriptionCell = pivotTableSheet.Cells[currentRowBeingExamined, DESCRIPTION_COL]; String desc = descriptionCell.Value.ToString(); if (contractItemDescs.Contains(desc)) { // args are firstRow, firstColumn, totalRows, totalColumns Range rangeToColorize = pivotTableSheet.Cells.CreateRange( currentRowBeingExamined, 0, ROWS_BETWEEN_DESCRIPTIONS, _grandTotalsColumnPivotTable + 2); Style style = workBook.Styles[workBook.Styles.Add()]; style.BackgroundColor = CONTRACT_ITEM_COLOR; StyleFlag styleFlag = new StyleFlag(); styleFlag.All = true; rangeToColorize.ApplyStyle(style, styleFlag); } currentRowBeingExamined = currentRowBeingExamined + ROWS_BETWEEN_DESCRIPTIONS; } } 

…但是，尽pipeif块已经达到好几次（比如“rangeToColorize”跨越了A28：E31），但是它并不“取”。 我的造型或风格标志或应用这些有什么问题？

UPDATE

即使我改变了这个：

 // Declare a style object. Style style; // Create/add the style object. style = workBook.CreateStyle(); // To Set the fill color of the range, you may use ForegroundColor with // Solid Pattern setting. style.BackgroundColor = CONTRACT_ITEM_COLOR; style.Pattern = BackgroundType.Solid; // Create a StyleFlag object. StyleFlag styleFlag = new StyleFlag(); // Make the corresponding attributes ON. styleFlag.Font = true; styleFlag.CellShading = true; // Apply the style to the range. rangeToColorize.ApplyStyle(style, styleFlag); 

…基于官方文件 ，它没有任何区别。

即使我改变了一些非常明确的关于一个特定单元的代码：

 cell = pivotTableSheet.Cells[4, 0]; cell.PutValue(AnnualContractProductsLabel); style = workBook.CreateStyle(); // cell.GetStyle(); style.HorizontalAlignment = TextAlignmentType.Center; style.VerticalAlignment = TextAlignmentType.Center; style.Font.IsBold = true; pivotTableSheet.Cells.SetRowHeight(4, 25); //style.BackgroundColor = CONTRACT_ITEM_COLOR; style.ForegroundColor = CONTRACT_ITEM_COLOR; pivotTableSheet.Cells[4, 0].SetStyle(style); 

… IOW，将“ style = cell.GetStyle（） ”改为“ style = workBook.CreateStyle（） ”和“ BackgroundColor ”为“ ForegroundColor ”，它什么都不做; 有问题的单元格没有着色。

那么（或者）一件奇怪的事情是我能够上色的唯一方法就是手动生成的“总计”列：

正如你所看到的，某些行已经根据条件进行了着色。 但是，只有在这一栏中，不应该在整个行上，因为它应该（至less在理论上）是：

 private void ColorizeContractItemBlocks(List<string> contractItemDescs) { int FIRST_DESCRIPTION_ROW = 7; int DESCRIPTION_COL = 0; int ROWS_BETWEEN_DESCRIPTIONS = 4; var pivot = pivotTableSheet.PivotTables[0]; var dataBodyRange = pivot.DataBodyRange; int currentRowBeingExamined = FIRST_DESCRIPTION_ROW; int rowsUsed = dataBodyRange.EndRow; pivot.RefreshData(); pivot.CalculateData(); // Loop through PivotTable data, colorizing contract items while (currentRowBeingExamined < rowsUsed) { Cell descriptionCell = pivotTableSheet.Cells[currentRowBeingExamined, DESCRIPTION_COL]; String desc = descriptionCell.Value.ToString(); if (contractItemDescs.Contains(desc)) { // args are firstRow, firstColumn, totalRows, totalColumns Range rangeToColorize = pivotTableSheet.Cells.CreateRange( currentRowBeingExamined, 0, ROWS_BETWEEN_DESCRIPTIONS, _grandTotalsColumnPivotTable + 2); // Declare a style object. Style style; // Create/add the style object. style = workBook.CreateStyle(); style.ForegroundColor = CONTRACT_ITEM_COLOR; //Color.Red; style.Pattern = BackgroundType.Solid; // Create a StyleFlag object. StyleFlag styleFlag = new StyleFlag(); // Make the corresponding attributes ON. styleFlag.Font = true; styleFlag.CellShading = true; // Apply the style to the range. rangeToColorize.ApplyStyle(style, styleFlag); } currentRowBeingExamined = currentRowBeingExamined + ROWS_BETWEEN_DESCRIPTIONS; } } 

所以这使我认为数据透视表不能被彩色化。 然而，即使当我尝试着色一个“普通的老”的单元格，如下所示：

 cell = pivotTableSheet.Cells[4, 0]; cell.PutValue(AnnualContractProductsLabel); style = workBook.CreateStyle(); style.HorizontalAlignment = TextAlignmentType.Center; style.VerticalAlignment = TextAlignmentType.Center; style.Font.IsBold = true; pivotTableSheet.Cells.SetRowHeight(4, 25); style.ForegroundColor = CONTRACT_ITEM_COLOR; // Create a StyleFlag object. StyleFlag styleFlag = new StyleFlag(); // Make the corresponding attributes ON. styleFlag.Font = true; styleFlag.CellShading = true; // Apply the style to the cell pivotTableSheet.Cells[4, 0].SetStyle(style, styleFlag); 

…它不起作用 – 不添加颜色。 为什么着色只能在一种情况下工作，而不是其他情况？

有了这个：

 PivotTableCollection pivotTables = pivotTableSheet.PivotTables; PivotTable pivotTable = pivotTables[0]; pivotTable.Format(); 

…我得到，“ 方法没有重载格式”需要0个参数。

…也简单地说：

 PivotTable.Format(); 

（大写“P”，没有“pivotTable”分配），我得到相同的错误信息。

即使有以下，根据另一个Aspose支持人员的build议，它什么都不做：

 private void ColorizeContractItemBlocks(List<string> contractItemDescs) { int FIRST_DESCRIPTION_ROW = 7; int DESCRIPTION_COL = 0; int ROWS_BETWEEN_DESCRIPTIONS = 4; var pivot = pivotTableSheet.PivotTables[0]; var dataBodyRange = pivot.DataBodyRange; int currentRowBeingExamined = FIRST_DESCRIPTION_ROW; int rowsUsed = dataBodyRange.EndRow; pivot.RefreshData(); pivot.CalculateData(); // Loop through PivotTable data, colorizing contract items while (currentRowBeingExamined < rowsUsed) { Cell descriptionCell = pivotTableSheet.Cells[currentRowBeingExamined, DESCRIPTION_COL]; String desc = descriptionCell.Value.ToString(); if (contractItemDescs.Contains(desc)) { Style style; style = workBook.CreateStyle(); style.ForegroundColor = CONTRACT_ITEM_COLOR; //Color.Red; style.Pattern = BackgroundType.Solid; StyleFlag styleFlag = new StyleFlag(); styleFlag.Font = true; styleFlag.CellShading = true; PivotTable pt = pivotTableSheet.PivotTables[0]; pt.Format(currentRowBeingExamined, 0, style); // test - does not work, either pt.Format(currentRowBeingExamined, 1, style); // " " //CellArea columnRange = pt.ColumnRange; //for (int c = columnRange.StartColumn; c < columnRange.EndColumn; c++) //{ // // pt.Format(columnRange.StartRow + 1, c, style); // pt.Format(currentRowBeingExamined, c, style); //} } currentRowBeingExamined = currentRowBeingExamined + ROWS_BETWEEN_DESCRIPTIONS; } }

现在，我已经使用了以下代码：

 private void ColorizeContractItemBlocks(List<string> contractItemDescs) { int FIRST_DESCRIPTION_ROW = 7; int DESCRIPTION_COL = 0; int ROWS_BETWEEN_DESCRIPTIONS = 4; var pivot = pivotTableSheet.PivotTables[0]; var dataBodyRange = pivot.DataBodyRange; int currentRowBeingExamined = FIRST_DESCRIPTION_ROW; int rowsUsed = dataBodyRange.EndRow; pivot.RefreshData(); pivot.CalculateData(); // Loop through PivotTable data, colorizing contract items while (currentRowBeingExamined < rowsUsed) { Cell descriptionCell = pivotTableSheet.Cells[currentRowBeingExamined, DESCRIPTION_COL]; String desc = descriptionCell.Value.ToString(); if (contractItemDescs.Contains(desc)) { Style style; style = workBook.CreateStyle(); style.BackgroundColor = CONTRACT_ITEM_COLOR; style.Pattern = BackgroundType.Solid; StyleFlag styleFlag = new StyleFlag(); styleFlag.Font = true; styleFlag.CellShading = true; PivotTable pt = pivotTableSheet.PivotTables[0]; pt.Format(currentRowBeingExamined, 0, style); pt.Format(currentRowBeingExamined, 1, style); CellArea columnRange = pt.ColumnRange; for (int c = columnRange.StartColumn; c <= columnRange.EndColumn; c++) { pt.Format(currentRowBeingExamined, c, style); pt.Format(currentRowBeingExamined+1, c, style); pt.Format(currentRowBeingExamined+2, c, style); pt.Format(currentRowBeingExamined+3, c, style); } } currentRowBeingExamined = currentRowBeingExamined + ROWS_BETWEEN_DESCRIPTIONS; } } 

…但是Data列的第二，第三和第四行没有被着色：

为什么不？ 我该如何解决？

更新7

我试图让列B的元素着色，并试图改变这一点：

 pt.Format(currentRowBeingExamined, 0, style); pt.Format(currentRowBeingExamined, 1, style); 

对此：

 pt.Format(currentRowBeingExamined, 0, style); pt.Format(currentRowBeingExamined, 1, style); pt.Format(currentRowBeingExamined, 2, style); // <= made no difference pt.Format(currentRowBeingExamined, 3, style); // " " 

…但没有区别。

那么我想知道上面的第一个两行代码是否有必要，但是注释这些代码导致列A / 0和B / 1根本不会着色：

以下是上下文中的当前代码：

 PivotTable pt = pivotTableSheet.PivotTables[0]; var style = workBook.CreateStyle(); while (currentRowBeingExamined < rowsUsed) { Cell descriptionCell = pivotTableSheet.Cells[currentRowBeingExamined, DESCRIPTION_COL]; String desc = descriptionCell.Value.ToString(); if (contractItemDescs.Contains(desc)) { style.BackgroundColor = CONTRACT_ITEM_COLOR; style.Pattern = BackgroundType.Solid; pt.Format(currentRowBeingExamined, 0, style); pt.Format(currentRowBeingExamined, 1, style); //pt.Format(currentRowBeingExamined, 2, style); <= made no difference //pt.Format(currentRowBeingExamined, 3, style); CellArea columnRange = pt.ColumnRange; for (int c = columnRange.StartColumn; c <= columnRange.EndColumn; c++) { pt.Format(currentRowBeingExamined, c, style); pt.Format(currentRowBeingExamined+1, c, style); pt.Format(currentRowBeingExamined+2, c, style); pt.Format(currentRowBeingExamined+3, c, style); } } currentRowBeingExamined = currentRowBeingExamined + ROWS_BETWEEN_DESCRIPTIONS; } 

那么我如何才能使彩色化涵盖所有栏目，包括“总购买量”，“平均价格总和”和“总计”百分比？

Answer 1

请更改以下两行

 Style style = workBook.CreateStyle(); style.BackgroundColor = CONTRACT_ITEM_COLOR; 

成

 Style style = workBook.CreateStyle(); style.ForegroundColor= CONTRACT_ITEM_COLOR; 

它应该解决你的问题。 让我们知道您的反馈。

更新2

请尝试以下两种专用于数据透视表的方法之一

 PivotTable.Format() PivotTable.FormatAll() 

更新5

对于PivotTable.Format（） ，您应该使用Style.BackgroundColor属性而不是Style.ForegroundColor属性。 所以改变你的路线

 style.ForegroundColor = CONTRACT_ITEM_COLOR; //Color.Red; 

至

 style.BackgroundColor = CONTRACT_ITEM_COLOR; //Color.Red; 

它应该解决你的问题。 谢谢。
