第13页底部还有空间文字没在当前页显示，而是在14页展示。这是什么原理呢

// 导出pdf
handleExport() {
this.loading = true
let _this = this
setTimeout(() => {
let spread = this.spread
let fontsObj = fonts;
_this.registerCustomFont(fontsObj);
_this.addFontsToFontManager(fontsObj);
_this.setPrintInfo(spread);
spread.savePDF(function (blob) {
saveAs(blob, 'EXITWIKI-WTM-20230809.pdf');
_this.loading = false
}, function (error) {
_this.$modal.alertError(error.errorMessage);
_this.loading = false
}, {});
}, 200)
},
registerCustomFont(fontsObj) {
var fonts = {
normal: fontsObj["simkai.ttf"],
};
GC.Spread.Sheets.PDF.PDFFontsManager.registerFont("楷体", fonts);
},
addFontsToFontManager(fontsObj) {
var fonts = {
normal: fontsObj["MTCORSVA.TTF"],
};
GC.Spread.Sheets.PDF.PDFFontsManager.fallbackFont = function (font) {
var fontInfoArray = font.split(" "),
fontName = fontInfoArray[fontInfoArray.length - 1];
if (fontName === "mtcorsva") {
return fonts.normal;
}
};
},
setPrintInfo(spread) {
for (let i = 0; i < spread.getSheetCount(); i++) {
var sheet = spread.getSheet(i)
var printInfo = sheet.printInfo();
sheet.suspendPaint();
printInfo.showBorder(false); // 是否显示边框
printInfo.showGridLine(false); // 是否打印网格线 (默认是打印)
printInfo.blackAndWhite(false); // 彩色打印
if (i == 0) {
printInfo.margin({top: -10, bottom: -10, left: -12, right: -50,}) // 边距
printInfo.columnEnd(12) // 打印截至至某一列
printInfo.rowEnd(62) // 打印截至至某一行
} else {
printInfo.columnEnd(6); // 打印截至至某一列
if (sheet.name() == '列表页-新增' || sheet.name() == '列表页-更新') {
let num = 4
if (num > 7) {
for (let j = 1; j <= (parseInt(num / 7)); j++) {
sheet.setRowPageBreak(j * 6 * 7 + (j * 2), true);
}
}
}
if (sheet.name() != '列表页-新增' && sheet.name() != '列表页-更新' && sheet.name() != '释义' && sheet.name() != '免责声明页') {
sheet.setRowPageBreak(43, true);
printInfo.rowEnd(79) // 打印截至至某一行
}
printInfo.headerCenter("EXITWIKI-WTM-20230809")
printInfo.footerCenter("&P/&N");
printInfo.firstPageNumber(null);
printInfo.margin({top: 100, left: 0, right: 0,bottom:55}) // 边距
printInfo.watermark([{x: 60, y: 20, width: 201, height: 48, imageSrc: this.images1, page: "all"}]);
printInfo.centering(GC.Spread.Sheets.Print.PrintCentering.horizontal); // 打印的居中方式
}
printInfo.qualityFactor(8); //打印质量，value为1~8的一个数值，越高则打印效果越好
sheet.resumePaint();
}
}
