SpreadJS允许您通过自定义按钮向工作表添加行或列。
可以显示或隐藏添加行或列按钮：
可以为按钮指定宽度、高度、样式和工具提示，添加行按钮选项仅支持height属性，添加列按钮仅支持width属性，并且仅支持样式的一些简单属性，如foreColor、backColor、hAlign、vAlign、backgroundImage、backgroundImageLayout，以在工作表上绘制。
如果需要自定义按钮的操作，可以为每个按钮指定命令：
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
var spreadNS = GC.Spread.Sheets;
var sheet = spread.getSheet(0);
sheet.suspendPaint();
sheet.options.addRowButtonOption.visible = true;
sheet.options.addColumnButtonOption.visible = true;
sheet.setRowCount(10);
sheet.setColumnCount(10);
sheet.resumePaint();
/*
* Show or hide the add row/column button.
*/
_getElementById("columnBtnVisible").addEventListener('click',function () {
var sheet = spread.getActiveSheet();
sheet.options.addColumnButtonOption.visible = this.checked;
spread.repaint();
});
_getElementById("rowBtnVisible").addEventListener('click',function () {
var sheet = spread.getActiveSheet();
sheet.options.addRowButtonOption.visible = this.checked;
spread.repaint();
});
/*
* Update the width/height of the add row/column button.
*/
_getElementById("columnBtnWidth").addEventListener('change',function () {
var sheet = spread.getActiveSheet();
sheet.options.addColumnButtonOption.width = parseInt(this.value);
spread.repaint();
});
_getElementById("rowBtnHeight").addEventListener('change',function () {
var sheet = spread.getActiveSheet();
sheet.options.addRowButtonOption.height = parseInt(this.value);
spread.repaint();
});
/*
* Update the tooltip of the add row/column button.
*/
_getElementById("columnBtnTooltip").addEventListener('input',function () {
var sheet = spread.getActiveSheet();
sheet.options.addColumnButtonOption.tooltip = this.value;
spread.repaint();
});
_getElementById("rowBtnTooltip").addEventListener('input',function () {
var sheet = spread.getActiveSheet();
sheet.options.addRowButtonOption.tooltip = this.value;
spread.repaint();
});
/*
* Update the style of the add row/column button.
*/
_getElementById("columnBtnBackColor").addEventListener('input',function () {
var sheet = spread.getActiveSheet();
var style = new GC.Spread.Sheets.Style();
style.backColor = this.value;
style.vAlign = GC.Spread.Sheets.VerticalAlign.center;
style.hAlign = GC.Spread.Sheets.HorizontalAlign.center;
sheet.options.addColumnButtonOption.style = style;
spread.repaint();
});
_getElementById("rowBtnBackColor").addEventListener('input',function () {
var sheet = spread.getActiveSheet();
var style = new GC.Spread.Sheets.Style();
style.backColor = this.value;
style.vAlign = GC.Spread.Sheets.VerticalAlign.center;
style.hAlign = GC.Spread.Sheets.HorizontalAlign.center;
sheet.options.addRowButtonOption.style = style;
spread.repaint();
});
// Define the command
const addRowCommand = sheet.options.addRowButtonOption.command;
spread.commandManager().register('clickRowButtonToDo', {
canUndo: false,
execute: function (context, options) {
// the self-defined command
options.cmd = addRowCommand;
spread.commandManager().execute(options);
}
});
sheet.options.addRowButtonOption.command = 'clickRowButtonToDo';
const addColumnCommand = sheet.options.addColumnButtonOption.command;
spread.commandManager().register('clickColumnButtonToDo', {
canUndo: false,
execute: function (context, options) {
// the self-defined command
options.cmd = addColumnCommand;
spread.commandManager().execute(options);
}
});
sheet.options.addColumnButtonOption.command = 'clickColumnButtonToDo';
};
function _getElementById(id) {
return document.getElementById(id);
}
