您还可以使用本博客中提到的实用方法:Getting cell witdth and height from excel with Apache POI。它可以解决你的问题。
从该博客复制并粘贴:
static public class PixelUtil {
public static final short EXCEL_COLUMN_WIDTH_FACTOR = 256;
public static final short EXCEL_ROW_HEIGHT_FACTOR = 20;
public static final int UNIT_OFFSET_LENGTH = 7;
public static final int[] UNIT_OFFSET_MAP = new int[] { 0, 36, 73, 109, 146, 182, 219 };
public static short pixel2WidthUnits(int pxs) {
short widthUnits = (short) (EXCEL_COLUMN_WIDTH_FACTOR * (pxs / UNIT_OFFSET_LENGTH));
widthUnits += UNIT_OFFSET_MAP[(pxs % UNIT_OFFSET_LENGTH)];
return widthUnits;
}
public static int widthUnits2Pixel(short widthUnits) {
int pixels = (widthUnits / EXCEL_COLUMN_WIDTH_FACTOR) * UNIT_OFFSET_LENGTH;
int offsetWidthUnits = widthUnits % EXCEL_COLUMN_WIDTH_FACTOR;
pixels += Math.floor((float) offsetWidthUnits / ((float) EXCEL_COLUMN_WIDTH_FACTOR / UNIT_OFFSET_LENGTH));
return pixels;
}
public static int heightUnits2Pixel(short heightUnits) {
int pixels = (heightUnits / EXCEL_ROW_HEIGHT_FACTOR);
int offsetWidthUnits = heightUnits % EXCEL_ROW_HEIGHT_FACTOR;
pixels += Math.floor((float) offsetWidthUnits / ((float) EXCEL_ROW_HEIGHT_FACTOR / UNIT_OFFSET_LENGTH));
return pixels;
}
}
因此,当您想要获取单元格宽度和高度时,您可以使用它来获取以像素为单位的值,值约为.
PixelUtil.heightUnits2Pixel((short) row.getHeight())
PixelUtil.widthUnits2Pixel((short) sh.getColumnWidth(columnIndex));
