SpreadJS Autofit Column with Minimum

Autofitting columns in a spreadsheet is a great way to ensure that all the data fits in the column width. In SpreadJS, you can use the autofitColumn method to automatically adjust the width of a column to fit the widest cell's content. But what if you want to set a minimum width for your column as well? Here's how to do it.

Using a Custom Function

You can use a custom function to calculate the maximum width of the content in a column and then add a minimum width to it. You can then use this value to set the width of the column using the autofitColumn method.

var sheet = new GC.Spread.Sheets.Worksheet();
var column = 0;
var minWidth = 100;

sheet.autoFitColumn(column, function (index, width) {
  return Math.max(width, minWidth);
});

In this example, we create a new worksheet and set the value of the column variable to 0. We also set the value of minWidth to 100, which is the minimum width we want for our column. We then call the autofitColumn method and pass in the column variable and a custom function that returns the maximum width of the content in the column or the minWidth value, whichever is greater.

Using the setStyle Method

You can also use the setStyle method to set the width of a column with a minimum value. First, you need to calculate the maximum width of the content in the column using a custom function. You can then create a new style object and set its width property to the maximum calculated width plus the minWidth value. Finally, you can use the setStyle method to set the style of the column to the new style object.

var sheet = new GC.Spread.Sheets.Worksheet();
var column = 0;
var minWidth = 100;

sheet.autoFitColumn(column, function (index, width) {
  return width;
});

var maxContentWidth = sheet.getActualColumnWidth(column);
var newWidth = Math.max(maxContentWidth, minWidth);

var style = new GC.Spread.Sheets.Style();
style.width = newWidth;

sheet.setStyle(0, column, style);

In this example, we create a new worksheet and set the value of the column variable to 0. We also set the value of minWidth to 100, which is the minimum width we want for our column. We then call the autofitColumn method to calculate the maximum width of the content in the column. We get the actual width of the column using the getActualColumnWidth method and store it in the maxContentWidth variable. We then calculate the new width by taking the maximum of the maxContentWidth and minWidth values. We create a new style object and set its width property to the new width value. Finally, we use the setStyle method to set the style of the column to the new style object.

Conclusion

In SpreadJS, you can use a custom function or the setStyle method to autofit a column with a minimum width. The custom function approach is simpler and more straightforward, while the setStyle approach gives you more control over the style of the column. Choose the approach that works best for your specific use case.
