JRT表格元素完全体

本文主要是介绍JRT表格元素完全体，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

之前分享的表格绘制是一个表格是实现雏形，周边把表格完全体实现，后面很多打印和绘制逻辑将借助此表格实现，所以需要表格够稳定够强大。

表格定义，后面借助模板设计器定义，现在是写死的测试定义对象。
1.PageList定义每页的起点坐标和换页行数或者换页坐标，以及是否画标题。弄这么个数组就是考虑有业务换页后画表格位置要不同，并且换页行数有变化，正常的话一页给一个页信息，如果没给对应序号页面的页信息，将按最后的PageList元素控制。
2.HeadCol定义标题的列信息，可以给标题单独知道加粗等。
3.DataCol定义数据列的信息，设置打印哪些列，每列的宽度和字体等。
4.Cols定义列数量，用于多列打印。
5.Padding和Font定义间距和字体。
6.RowHeight定义行高。

{"PageList": [{"Left": 10,"Top": 40,"ChangePageRowNum": 14,"ChangePageY": 1000,"DrawHead": true}, {"Left": 30,"Top": 100,"ChangePageRowNum": 0,"ChangePageY": 600,"DrawHead": true}],"Cols": 1,"RowHeight": 20,"PaddingTop": 4,"PaddingLeft": 4,"PaddingRight": 4,"PaddingBottom": 4,"BoderWidth": 1,"PrintFont": "宋体","PrintFontSize": "12","PrintFontStyle": "","HeadCol": [{"DataField": "Col0","Text": "","Width": 150,"PrintAlignment": "","PrintFont": null,"PrintFontSize": null,"PrintFontStyle": "Bold","PrintColor": ""}, {"DataField": "Col1","Text": "","Width": 150,"PrintAlignment": "","PrintFont": null,"PrintFontSize": null,"PrintFontStyle": "Bold","PrintColor": ""}, {"DataField": "Col2","Text": "","Width": 150,"PrintAlignment": "","PrintFont": null,"PrintFontSize": null,"PrintFontStyle": "Bold","PrintColor": ""}, {"DataField": "Col3","Text": "","Width": 150,"PrintAlignment": "","PrintFont": null,"PrintFontSize": null,"PrintFontStyle": "Bold","PrintColor": ""}, {"DataField": "Col4","Text": "","Width": 150,"PrintAlignment": "","PrintFont": null,"PrintFontSize": null,"PrintFontStyle": "Bold","PrintColor": ""}],"DataCol": [{"DataField": "Col0","Text": "","Width": 150,"PrintAlignment": "","PrintFont": null,"PrintFontSize": null,"PrintFontStyle": null,"PrintColor": ""}, {"DataField": "Col1","Text": "","Width": 150,"PrintAlignment": "","PrintFont": null,"PrintFontSize": null,"PrintFontStyle": null,"PrintColor": ""}, {"DataField": "Col2","Text": "","Width": 150,"PrintAlignment": "","PrintFont": null,"PrintFontSize": null,"PrintFontStyle": null,"PrintColor": ""}, {"DataField": "Col3","Text": "","Width": 150,"PrintAlignment": "","PrintFont": null,"PrintFontSize": null,"PrintFontStyle": null,"PrintColor": ""}, {"DataField": "Col4","Text": "","Width": 150,"PrintAlignment": "","PrintFont": null,"PrintFontSize": null,"PrintFontStyle": null,"PrintColor": ""}]
}

表格绘制API定义，传入定义和标题级表格数据，这里加了表格换页回调接口和表格唯一键，换页前后会执行回调，如果不为null的话。
