changeColumns (wbk, columns, callback);
wbk. Sets workbook value.
columns. Sets columns.
callback. Sets operation completion handler.
The changeColumns method changes workbook columns.
To execute the example, the page must contain the WorkbookBox component named workbookBox (see Example of Creating the WorkbookBox Component), and also add the following code in the handler, that processes document opening event:
var changeColumnsButt = new PP.Ui.Button({
ParentNode: document.body, //DOM parent node
Content: "Change Column", //text
Click: PP.Delegate(onClickChangeColumnsButt)
});
function onClickChangeColumnsButt()
{
var source = workbookBox.getSource();//Return an instance of the PP.TS.WbkDocument class
var columns = wbk.getWbkMetadata().columns;
//Change text on the column header
columns.its.it[0].customTitle = 'Column changed';
//Change workbook columns
tsService.changeColumns(wbk, columns, PP.Delegate(onColumnsChanged, this));
//changeColumns function end event handler
function onColumnsChanged(sender, args){
//Refresh the workbookBox component
workbookBox.refreshAll();
}
}
After executing the example a button named Change Column is placed in the HTML page. On clicking this button heading of the workbook table column is changed to Column Changed:
