A File widget. Double click to open it and select the dataset file. The output of the File widget. The input of the Data Table widget. The communication channel. It passes the dataset from the File widget to the Data Table. A Data Table widget. Double click the icon to see the data in a spreadsheet. The output of the Data Table to send out any data (rows) that are selected to the widget. This output is not used, hence dashed line. You can add another Data Table by clicking on its icon from the toolbox on the left, connect the ouput of Data Table to the input of new Data Table (1) and check if the selected data from Data Table is indeed sent to the downstream widget. This demo works best if both widgets are open, that is, their windows displayed. gAN9cQAoWBIAAABjb250cm9sQXJlYVZpc2libGVxAYhYDAAAAHJlY2VudF9wYXRoc3ECXXEDY09y YW5nZS53aWRnZXRzLnV0aWxzLmZpbGVkaWFsb2dzClJlY2VudFBhdGgKcQQpgXEFfXEGKFgHAAAA YWJzcGF0aHEHWDAAAAAvVXNlcnMvYW56ZS9kZXYvb3JhbmdlMy9PcmFuZ2UvZGF0YXNldHMvaXJp cy50YWJxCFgGAAAAcHJlZml4cQlYDwAAAHNhbXBsZS1kYXRhc2V0c3EKWAcAAAByZWxwYXRocQtY CAAAAGlyaXMudGFicQxYBQAAAHRpdGxlcQ1YAAAAAHEOWAUAAABzaGVldHEPaA5YCwAAAGZpbGVf Zm9ybWF0cRBOdWJhWAsAAAByZWNlbnRfdXJsc3ERXXESWBMAAABzYXZlZFdpZGdldEdlb21ldHJ5 cRNDLgHZ0MsAAQAAAAACEwAAATwAAAOqAAACNQAAAhMAAAFSAAADqgAAAjUAAAAAAABxFFgLAAAA c2hlZXRfbmFtZXNxFX1xFlgGAAAAc291cmNlcRdLAFgDAAAAdXJscRhoDlgNAAAAZG9tYWluX2Vk aXRvcnEZfXEaWAsAAABfX3ZlcnNpb25fX3EbSwFYEAAAAGNvbnRleHRfc2V0dGluZ3NxHF1xHWNP cmFuZ2Uud2lkZ2V0cy5zZXR0aW5ncwpDb250ZXh0CnEeKYFxH31xIChYBAAAAHRpbWVxIUdB1qcW DLpbX1gGAAAAdmFsdWVzcSJ9cSMoWAkAAAB2YXJpYWJsZXNxJF1xJVgJAAAAeGxzX3NoZWV0cSZo Dkr/////hnEnaBl9cShoJF1xKShdcSooWAwAAABzZXBhbCBsZW5ndGhxK2NPcmFuZ2UuZGF0YS52 YXJpYWJsZQpDb250aW51b3VzVmFyaWFibGUKcSxLAGgOiGVdcS0oWAsAAABzZXBhbCB3aWR0aHEu aCxLAGgOiGVdcS8oWAwAAABwZXRhbCBsZW5ndGhxMGgsSwBoDohlXXExKFgLAAAAcGV0YWwgd2lk dGhxMmgsSwBoDohlXXEzKFgEAAAAaXJpc3E0Y09yYW5nZS5kYXRhLnZhcmlhYmxlCkRpc2NyZXRl VmFyaWFibGUKcTVLAVgsAAAASXJpcy1zZXRvc2EsIElyaXMtdmVyc2ljb2xvciwgSXJpcy12aXJn aW5pY2FxNollZXNoG0sBdVgKAAAAYXR0cmlidXRlc3E3KFgMAAAAc2VwYWwgbGVuZ3RocThLAoZx OVgLAAAAc2VwYWwgd2lkdGhxOksChnE7WAwAAABwZXRhbCBsZW5ndGhxPEsChnE9WAsAAABwZXRh bCB3aWR0aHE+SwKGcT90cUBYBQAAAG1ldGFzcUEpWAoAAABjbGFzc192YXJzcUJYBAAAAGlyaXNx Q11xRChYCwAAAElyaXMtc2V0b3NhcUVYDwAAAElyaXMtdmVyc2ljb2xvcnFGWA4AAABJcmlzLXZp cmdpbmljYXFHZYZxSIVxSVgSAAAAbW9kaWZpZWRfdmFyaWFibGVzcUpdcUt1YmF1Lg== gAN9cQAoWAsAAABhdXRvX2NvbW1pdHEBiFgOAAAAY29sb3JfYnlfY2xhc3NxAohYEgAAAGNvbnRy b2xBcmVhVmlzaWJsZXEDiFgOAAAAZGlzdF9jb2xvcl9SR0JxBChL3EvcS9xL/3RxBVgTAAAAc2F2 ZWRXaWRnZXRHZW9tZXRyeXEGTlgLAAAAc2VsZWN0X3Jvd3NxB4hYFQAAAHNob3dfYXR0cmlidXRl X2xhYmVsc3EIiFgSAAAAc2hvd19kaXN0cmlidXRpb25zcQmJWAsAAABfX3ZlcnNpb25fX3EKSwFY EAAAAGNvbnRleHRfc2V0dGluZ3NxC11xDGNPcmFuZ2Uud2lkZ2V0cy5zZXR0aW5ncwpDb250ZXh0 CnENKYFxDn1xDyhYBgAAAHZhbHVlc3EQfXERKFgNAAAAc2VsZWN0ZWRfY29sc3ESXXETWA0AAABz ZWxlY3RlZF9yb3dzcRRdcRVoCksBdVgFAAAAbWV0YXNxFn1xF1gOAAAAb3JkZXJlZF9kb21haW5x GF1xGShYDAAAAHNlcGFsIGxlbmd0aHEaSwKGcRtYCwAAAHNlcGFsIHdpZHRocRxLAoZxHVgMAAAA cGV0YWwgbGVuZ3RocR5LAoZxH1gLAAAAcGV0YWwgd2lkdGhxIEsChnEhWAQAAABpcmlzcSJLAYZx I2VYCgAAAGF0dHJpYnV0ZXNxJH1xJShoIEsCaBpLAmgeSwJoIl1xJihYCwAAAElyaXMtc2V0b3Nh cSdYDwAAAElyaXMtdmVyc2ljb2xvcnEoWA4AAABJcmlzLXZpcmdpbmljYXEpZWgcSwJ1WAQAAAB0 aW1lcSpHQdanFgy9pBZ1YmF1Lg==
