在excel中将表格copy线变为深黑色，可在表格边框设置中将边框线条颜色设置为深黑色。
方法步骤如下：百
1、打开需要操作的EXCEL表格，选中需要把边框线改为黑色的单元格，点击“字体”上面边框旁边的度下拉按钮。
2、在下拉选项中选点击“线条颜色”，并在右侧颜色选项中点击“黑色问”。
3、继续点击“边框”旁边的下拉按钮，点击“所有框线”即可。
4、返回EXCEL表格，可发现已成功将EXCEL的表格线变为深答黑色
HSSFCellStyle style = hwb.createCellStyle();
设置边框抄颜色（袭上下左右线百条度设置为问黑色）答
style.setTopBorderColor(HSSFColor.BLACK.index);
style.setBottomBorderColor(HSSFColor.BLACK.index);
style.setLeftBorderColor(HSSFColor.BLACK.index);
style.setRightBorderColor(HSSFColor.BLACK.index);

Java中设置表格边线颜色：
import com.spire.xls.*;
import java.awt.*;
public class AddBorders {
public static void main(String[] args){
//Create a workbook instance
Workbook workbook = new Workbook();
//Load the Excel file
workbook.loadFromFile("Sample-SetBorder.xlsx");
//Get the first worksheet
Worksheet sheet = workbook.getWorksheets().get(0);
//Get the cell range that you want to apply border style
CellRange cr = sheet.getCellRange(sheet.getFirstRow(), sheet.getFirstColumn(), sheet.getLastRow(), sheet.getLastColumn());
//Apply border style
cr.getBorders().setLineStyle(LineStyleType.Double);
cr.getBorders().getByBordersLineType(BordersLineType.DiagonalDown).setLineStyle(LineStyleType.None);
cr.getBorders().getByBordersLineType(BordersLineType.DiagonalUp).setLineStyle(LineStyleType.None);
cr.getBorders().setColor(Color.BLUE);
//Save the resultant file
workbook.saveToFile("SetBorder.xlsx", ExcelVersion.Version2010);
}
}
