# Description

The plugin allows to trim certain rows. The trimming is achieved by applying the transformation algorithm to the data transformation. In this case, when the row is trimmed it is not accessible using getData* methods thus the trimmed data is not visible to other plugins.

Example

const container = document.getElementById('example');
const hot = new Handsontable(container, {
  data: getData(),
  // hide selected rows on table initialization
  trimRows: [1, 2, 5]
});

// access the trimRows plugin instance
const trimRowsPlugin = hot.getPlugin('trimRows');

// hide single row
trimRowsPlugin.trimRow(1);

// hide multiple rows
trimRowsPlugin.trimRow(1, 2, 9);

// or as an array
trimRowsPlugin.trimRows([1, 2, 9]);

// show single row
trimRowsPlugin.untrimRow(1);

// show multiple rows
trimRowsPlugin.untrimRow(1, 2, 9);

// or as an array
trimRowsPlugin.untrimRows([1, 2, 9]);

// rerender table to see the changes
hot.render();
