Aspose.Cells FOSS
Java
Validation

Javaでバリデーションを扱う方法

概要

Aspose.Cells FOSS for Java はデータ検証ルールと条件付き書式設定をサポートしています。これらの機能を使用して、入力制約を強制し、Excel のデータをハイライトします。

整数の検証ルールを追加 

import com.aspose.cells_foss.CellArea;
import com.aspose.cells_foss.OperatorType;
import com.aspose.cells_foss.Validation;
import com.aspose.cells_foss.ValidationType;
import com.aspose.cells_foss.Workbook;
import com.aspose.cells_foss.Worksheet;

try (Workbook workbook = new Workbook()) {
    Worksheet sheet = workbook.getWorksheets().get(0);
    int vi = sheet.getValidations().add(new CellArea(1, 0, 10, 0));
    Validation validation = sheet.getValidations().get(vi);
    validation.setType(ValidationType.WHOLE_NUMBER);
    validation.setOperator(OperatorType.BETWEEN);
    validation.setFormula1("1");
    validation.setFormula2("100");
    workbook.save("validated.xlsx");
}

条件付き書式を追加

条件に一致するセルに太字書式を適用する:

import com.aspose.cells_foss.CellArea;
import com.aspose.cells_foss.FormatCondition;
import com.aspose.cells_foss.FormatConditionCollection;
import com.aspose.cells_foss.FormatConditionType;
import com.aspose.cells_foss.OperatorType;
import com.aspose.cells_foss.Style;
import com.aspose.cells_foss.Workbook;
import com.aspose.cells_foss.Worksheet;

try (Workbook workbook = new Workbook()) {
    Worksheet sheet = workbook.getWorksheets().get(0);
    int cfIndex = sheet.getConditionalFormattings().add();
    FormatConditionCollection conditions = sheet.getConditionalFormattings().get(cfIndex);
    conditions.addArea(CellArea.createCellArea("B2", "B11"));
    int condIndex = conditions.addCondition(
        FormatConditionType.CELL_VALUE, OperatorType.BETWEEN, "1", "100");
    FormatCondition condition = conditions.get(condIndex);
    Style style = condition.getStyle();
    style.getFont().setBold(true);
    condition.setStyle(style);
    workbook.save("conditional.xlsx");
}
