            0: { text: 'testingtesttestetst' },
            2: { text: 'testing' },
          },
        },
        2: {
          cells: {
            0: { text: 'render', style: 0 },
            1: { text: 'Hello' },

          }
        },
        8: {
          cells: {
            8: { text: 'border test', style: 0 },
          }
        }
      },

Create a new spreadsheet in the container element you created.

const mySpreadSheet = new Spreadsheet(document.getElementById('demo')).loadData(myData);

Save the data after changed.

mySpreadSheet.change(data => {
  // save data to db
});

Validate the data.

mySpreadSheet.validate();

Possible options. Override the default values and pass the options object as the second parameter to the Spreadsheet function.

const mySpreadSheet = new Spreadsheet(document.getElementById('demo'),{
        mode: 'edit', // edit | read
        showToolbar: true,
        showGrid: true,
        showContextmenu: true,
        view: {
          height: () => document.documentElement.clientHeight,
          width: () => document.documentElement.clientWidth,
        },
        row: {
          len: 100,
          height: 25,
        },
        col: {
          len: 26,
          width: 100,
          indexWidth: 60,
          minWidth: 60,
        },
        style: {
          bgcolor: '#ffffff',
          align: 'left',
          valign: 'middle',
          textwrap: false,
