ExcelLibrary 是一个比较精致的 Excel 读写组件，还是由国人开发的。可以读写 xls 和 xlsx 格式的 Excel。支持简单的公式，可插入图片，对于格式的设置也不是很丰富，可设置单元格宽度，数据格式化显示。对字体，前景、背景色进行设置是它的局限性。 虽比不上 NPOI，但作为小巧的用来读写纯数据内容的 Excel 还是很高效的。-ExcelLibrary Excel is a more sophisticated reading and writing component, or developed by the people. Can read and write xls and xlsx format Excel. Support the simple formula that can insert a picture, the setting for the format is not very rich, you can set the cell width, the data format display. The font, foreground, background color set is its limitations. Although not as NPOI, but as a small net used to read and write Excel data content is still very efficient.
