Summaries & Aggregations

Rowstack provides built-in support for calculating and displaying summaries at the bottom of each column. This is essential for financial data, inventory tracking, and any metric-driven application.

#Supported Aggregations

Rowstack currently supports the following aggregation types:

• Sum: Calculates the total for numeric values.
• Average: Calculates the arithmetic mean.
• Count: Counts the number of non-empty cells in the column.

#Enabling Summaries

Summaries are displayed in a sticky footer at the bottom of the table. You can enable or disable the footer globally:

const config = {
  footer: {
    enabled: true
  }
};

#Configuring Aggregations

Each column can have its own summary type defined. Currently, users can select the summary type directly from the column header popup or view them in the footer.

#Summary Footer

The footer remains visible even as you scroll through large datasets, ensuring that your key metrics are always in view.

#Integration with Filtering

Aggregations in Rowstack are dynamic. If you apply a Filter, the summaries will automatically update to reflect only the currently visible (filtered) records.

#Integration with Grouping

When data is grouped, Rowstack can display summaries for each group, allowing you to see totals for specific categories at a glance.
