SpreadJS結(jié)合40余年專業(yè)控件技術(shù)和在電子表格應(yīng)用領(lǐng)域的經(jīng)驗(yàn)而推出的純前端表格控件，基于 HTML5，兼容 450 多種 Excel 公式，具備“高性能、跨平臺、與 Excel 高度兼容”的產(chǎn)品特性，備受華為、明源云、遠(yuǎn)光軟件等知名企業(yè)青睞，被中國軟件行業(yè)協(xié)會認(rèn)定為“中國優(yōu)秀軟件產(chǎn)品”。SpreadJS在界面和功能上與 Excel 高度類似，但又不局限于 Excel，而是為企業(yè)信息化系統(tǒng)提供 表格文檔協(xié)同編輯、 數(shù)據(jù)填報(bào) 和 類 Excel 報(bào)表設(shè)計(jì) 的應(yīng)用場景支持，極大降低了企業(yè)研發(fā)成本和項(xiàng)目交付風(fēng)險(xiǎn)。

 甘特圖是項(xiàng)目管理、生產(chǎn)排程、節(jié)點(diǎn)管理中非常常見的一個(gè)功能。那么，有沒有一種方法能夠幫助將甘特圖引入到系統(tǒng)中，讓數(shù)據(jù)的進(jìn)度、排程數(shù)據(jù)的展示更加直觀，讓管理更加高效。

今天為大家?guī)硪粋€(gè)新的插件——甘特圖插件。該插件是結(jié)合 SpreadJS 本身強(qiáng)大的前端電子表格能力提供的一種全新的可視化展示方案，能夠有效地將生產(chǎn)計(jì)劃、預(yù)算排期中的日程管理信息展示出來，顯示關(guān)鍵路徑上關(guān)鍵節(jié)點(diǎn)的進(jìn)展或狀態(tài)。其數(shù)據(jù)來自與集算表同源的數(shù)據(jù)管理器（DataManager），通過綁定 -> 視圖的方式，將層級化的任務(wù)數(shù)據(jù)通過甘特圖插件進(jìn)行展示。通過這種結(jié)合，前端Excel的便捷錄入體驗(yàn)和甘特圖的可視化展示可以無縫的集合在一起，使得系統(tǒng)更易于使用。

6. 導(dǎo)入和導(dǎo)出操作

支持將甘特圖插件中展示的內(nèi)容導(dǎo)出至PDF及Excel的格式。

總結(jié)

甘特圖是一種強(qiáng)大的項(xiàng)目管理工具，通過直觀的時(shí)間軸展示任務(wù)的安排和進(jìn)度。它能幫助項(xiàng)目經(jīng)理們創(chuàng)建詳細(xì)的項(xiàng)目計(jì)劃，有效跟蹤進(jìn)度，并合理分配資源。甘特圖還可以管理任務(wù)間的依賴關(guān)系，及時(shí)調(diào)整時(shí)間表，并識別風(fēng)險(xiǎn)與關(guān)鍵路徑。它在項(xiàng)目管理中扮演著重要的角色，提高了團(tuán)隊(duì)的協(xié)作效率和項(xiàng)目的成功率。通過使用甘特圖，項(xiàng)目團(tuán)隊(duì)能夠更好地掌握項(xiàng)目進(jìn)展，作出決策，并確保項(xiàng)目按時(shí)交付。以上功能可以通過前端表格組件 SpreadJS 新晉的甘特圖插件方便的添加到系統(tǒng)中。
