Custom Table

This sample shows how you can operate the table in worksheet, you might want to get the table to customize it, move the table to another range, resize it, or remove it.

To get a table, use the find, findByName, or all method. For example: If you want to change the table location or change the table size, you can use the move method to change the location, and the resize method to resize it. For example: If you don't need the table, you can remove it using the remove method. For example:
window.onload = function () { var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss")); initSpread(spread); }; function initSpread(spread) { spread.suspendPaint(); var spreadNS = GC.Spread.Sheets; var sheet = spread.getSheet(0); sheet.bind(spreadNS.Events.SelectionChanged, selectionChangedCallback); var table = sheet.tables.add("table1", 1, 1, 4, 4, spreadNS.Tables.TableThemes.light1); sheet.setColumnWidth(1, 120); sheet.setColumnWidth(2, 120); sheet.setColumnWidth(3, 120); sheet.setColumnWidth(4, 120); sheet.getCell(1, 1).text("First Name"); sheet.getCell(1, 2).text("Last Name"); sheet.getCell(1, 3).text("Score"); sheet.getCell(1, 4).text("Position"); sheet.getCell(2, 1).text("Alexa"); sheet.getCell(2, 2).text("Wilder"); sheet.getCell(2, 3).text("90"); sheet.getCell(2, 4).text("Web Developer"); sheet.getCell(3, 1).text("Victor"); sheet.getCell(3, 2).text("Wooten"); sheet.getCell(3, 3).text("70"); sheet.getCell(3, 4).text(".NET Developer"); sheet.getCell(4, 1).text("Ifeoma"); sheet.getCell(4, 2).text("Mays"); sheet.getCell(4, 3).text("85"); sheet.getCell(4, 4).text("Sales Manager"); spread.resumePaint(); function selectionChangedCallback() { var sheet = spread.getActiveSheet(); var table = sheet.tables.find(sheet.getActiveRowIndex(), sheet.getActiveColumnIndex()); if (table && table.name) { _getElementById("removeTable").removeAttribute('disabled'); valueCheckCallback("moveRow", "moveColumn", "moveTable"); valueCheckCallback("resizeRow", "resizeColumn", "resizeTable"); } else { _getElementById("removeTable").setAttribute('disabled', true); _getElementById("moveTable").setAttribute('disabled', true); _getElementById("resizeTable").setAttribute('disabled', true); } } function valueCheckCallback(rowElementId, columnElementId, targetElementID) { var rowInfo = parseInt(_getElementById("" + rowElementId).value); var columnInfo = parseInt(_getElementById("" + columnElementId).value); var targetElement = _getElementById("" + targetElementID); if (isNaN(rowInfo) || isNaN(columnInfo)) { targetElement.setAttribute('disabled', true); } else { targetElement.removeAttribute('disabled'); } } function removeTableFromOptionList(tableName) { var removeNode = document.querySelector("option[value=" + tableName + "]"); if (removeNode) { removeNode.parentNode.removeChild(removeNode); } } //add table _getElementById("addTable").addEventListener('click',function () { var sheet = spread.getActiveSheet(); try { var cr = sheet.getSelections()[0]; if (cr) { cr = getActualRange(cr, sheet.getRowCount(), sheet.getColumnCount()); var tableName = getTableName(sheet); sheet.tables.add(tableName, cr.row, cr.col, cr.rowCount, cr.colCount, spreadNS.Tables.TableThemes.light1); } } catch (ex) { alert(!!ex.message ?
