Usage

The following sections will introduce usages of some noticeable features which are all Available in ZK Spreadsheet EE only.

Special Paste

In addition to normal pasting, Spreadsheet also provides other special pasting on toolbar.

You can select "Paste Special" to access all available pasting options in a dialog.

Custom Sort

The "Ascending" and "Descending" function can sort data by only one column but "Custom sort" can sort data by multiple columns.

After selecting "Custom sort" on the toolbar, a dialog appears. You can add sorting criteria at most to 3 columns. If your data includes column headings, make sure the "My data has headers" option is checked.

The sorting result of criteria above:

Filter

The Filter can screen out data you don't want quickly and easily. We usually select the cells we want to filter first and select "Filter" on the toolbar.

Then each column will have a drop-down button. Click the drop-down button to select data to filter.

Those rows that contain the unchecked item will not appear in the original table unless you check them back.

If you insert more data after applying a filter, you can select "Reapply" on the toolbar to apply same criteria to new data.

Auto Fill

Auto fill is a handy feature to fill cells with data in particular pattern based on selected cells. Text will be copied and numbers and dates will be increased (or decreased).

To use this, You should select one or more cells and drag the fill handle across or down the cells that you want to fill.

Fill cells after dragging right.

Format Cell

In context menu appeared when right clicking a cell, "Format Cell" provides 10 different categories with total 47 formats to apply on cells.

Validation

Spreadsheet can read your validation settings in an Excel file and show hints and validate input for you. (OSE will ignore validation settings.)

When you select a cell with validation settings, Spreadsheet will display input message aside the cell.

If you enter invalid data, Spreadsheet will prompt you with the error message you set in the Excel file.

If your validation criteria comes from a range of data, you can input that cell via drop-down list.
