選項卡允許試算表使用者在資料集之間快速移動，從而在多個資料部分之間提供清晰的視覺區分。

Worksheet tabs act as a visual and interactive index, enabling users to seamlessly navigate between distinct sections within a single workbook. This efficient organization facilitates data comparison and analysis. The clear visual distinction between tabs reduces cognitive load and enhances comprehension, making it easier for users to grasp the overall structure and navigate the information within the workbook.

Several React Spreadsheet controls offer support for tabs including:

  • Telerik Spreadsheet React (part of KendoReact) enables users to effortlessly navigate between spreadsheets through designated tabs.
  • SpreadJS by MESCIUS empowers developers with tabbed navigation for efficient data organization within their React applications.
  • Infragistics Spreadsheet React enables users to effortlessly navigate between spreadsheets through designated tabs.
  • Syncfusion Spreadsheet JavaScript provides tab-based navigation for a familiar and user-friendly experience when working with multiple sheets.

在計算過程中保持試算表的回應速度

SpreadJS 17.1.0 引入了增量計算，即使在最複雜的資料處理中也有助於保持試算表的性能。

SpreadJS by MESCIUS is a JavaScript library offering a comprehensive spreadsheet solution for enterprise web applications. It delivers an Excel-like user experience with features like data tables, extensive charting, formatting options, and a powerful formula engine supporting over 500 functions. SpreadJS integrates with popular frameworks like React, Angular, and Vue.js, enabling developers to build high-performance, customizable spreadsheet functionalities within their web applications.

The SpreadJS v17.1 release enables incremental computation, which breaks down the entire calculation into pieces during execution. This enables responsiveness to user actions when the calculation task is large, preventing the UI from being unresponsive when a workbook has many formulas. Developers will only need to set the incrementalCalculation attribute of the Workbook class to true. This computation procedure is also displayed in the status bar.

To see a full list of what's new in 17.1.0, see our release notes.

SpreadJS is licensed per developer and includes 1 Year Maintenance (major and minor version releases and unlimited support phone calls). SpreadJS requires an Annual or Perpetual Deployment License. The optional Add-ons are available at an additional cost, and require a SpreadJS license. See our SpreadJS licensing page for full details.
