感谢高级互助大佬(用户k6280494)提供的决策表实现方式:

另外通过个人研究:得到普通报表添加水印的方式(直接放到web初始化属性中即可):
function
watermark(settings) {
//默认设置
var defaultSettings = {
watermark_txt: "",
watermark_x: 20, //水印起始位置x轴坐标
watermark_y: 20, //水印起始位置Y轴坐标
watermark_rows: 20, //水印行数
watermark_cols: 20, //水印列数
watermark_x_space: 100, //水印x轴间隔
watermark_y_space: 50, //水印y轴间隔
watermark_color: '#aaa', //水印字体颜色
watermark_alpha: 0.4, //水印透明度
watermark_fontsize: '15px', //水印字体大小
watermark_font: '微软雅黑',
//水印字体
watermark_width: 210, //水印宽度
watermark_height: 80, //水印长度
watermark_angle: 20 //水印倾斜度数
};
$.extend(defaultSettings, settings ===
undefined ? {} : settings);
let newText = "";
for (let i = 0; i <
defaultSettings.watermark_txt.length; i++) {
if (i % 2 !== 0) {
newText += " ";
}
newText +=
defaultSettings.watermark_txt[i];
}
defaultSettings.watermark_txt = newText;
//根据函数的入参调整设置
if (arguments.length === 1 &&
typeof arguments[0] === "object") {
var src = arguments[0] || {};
for (key in src) {
if (src[key] &&
defaultSettings[key] && src[key] === defaultSettings[key]) continue;
else if (src[key])
defaultSettings[key] = src[key];
}
}
//创建虚拟节点对象,在该节点对象中可以放元素,最后只需在页面中添加该节点对象即可。可提高性能
var oTemp =
document.createDocumentFragment();
//获取页面最大宽度
var page_width =
Math.max(document.body.scrollWidth, document.body.clientWidth);
var cutWidth = page_width * 0.0150;
var page_width = page_width - cutWidth;
//获取页面最大高度
var page_height =
Math.max(document.body.scrollHeight, document.body.clientHeight) + 450;
page_height = Math.max(page_height,
window.innerHeight - 30);
//如果将水印列数设置为0,或水印列数设置过大,超过页面最大宽度,则重新计算水印列数和水印x轴间隔
if (defaultSettings.watermark_cols == 0 ||
(parseInt(defaultSettings.watermark_x + defaultSettings

.watermark_x_space) /

defaultSettings.watermark_x_space =
parseInt((page_width - defaultSettings.watermark_x - defaultSettings
.watermark_width *
defaultSettings.watermark_cols) / (defaultSettings.watermark_cols - 1));
}
//如果将水印行数设置为0,或水印行数设置过大,超过页面最大长度,则重新计算水印行数和水印y轴间隔
if (defaultSettings.watermark_rows == 0 ||
(parseInt(defaultSettings.watermark_y + defaultSettings
.watermark_height *
defaultSettings.watermark_rows + defaultSettings.watermark_y_space * (
defaultSettings.watermark_rows - 1))
> page_height)) {
defaultSettings.watermark_rows =

.watermark_y) /

defaultSettings.watermark_y_space =
