LabWindows/CVI中table的主要用法
2016年12月20日 狄阁老
Table是在各种开发环境中一个很重要的控件，特别是在测试软件中，table是一个重要的结果显示控件，下面来介绍一下table的主要功能：（最后附有效果视频）
一、要使用table首先需要插入行列，插入列的函数：
1）int InsertTableColumns (int Panel_Handle, int Control_ID, int Column_Index, int Number_of_Columns, int Cell_Type);
例如： InsertTableColumns VAL_CELL_STRING);
(panelHandle, PANEL_TABLE, 1, 5,
上面是插入5列，每列为string类型；
2）int InsertTableRows (int Panel_Handle, int Control_ID, int Row_Index, int Number_of_Rows, int Cell_Type);
例如：InsertTableRows (panelHandle, PANEL_TABLE, -1, 1, VAL_CELL_STRING);
每次都是从最后一行插入新行；
二、设置列首：
可以双击table控件，设置列首，这个就固定死了，用代码实现还是比较自由可控的
要设置列首，需要将列首设置为可用状态：
SetTableColumnAttribute ATTR_USE_LABEL_TEXT, 1);
(panelHandle, PANEL_TABLE,columnindex,
当有多列要设置，每列需要启用，用一个for循环启用，例如：
//启用列名,5列，用个循环将列名启动起来
for(i=1;i<6;i++)
SetTableColumnAttribute ATTR_USE_LABEL_TEXT, 1);
(panelHandle, PANEL_TABLE, i,
再设置列首名称：
例如：1~5列的列名设置为测试项名称，测试值，理论值，单位，测试结果
SetTableColumnAttribute (panelHandle, PANEL_TABLE, 1, ATTR_LABEL_TEXT, \"测试项名称\");
SetTableColumnAttribute (panelHandle, PANEL_TABLE, 2, ATTR_LABEL_TEXT, \"测试值\");
SetTableColumnAttribute (panelHandle, PANEL_TABLE, 3, ATTR_LABEL_TEXT, \"理论值\");
SetTableColumnAttribute (panelHandle, PANEL_TABLE, 4, ATTR_LABEL_TEXT, \"单位\");
SetTableColumnAttribute (panelHandle, PANEL_TABLE, 5, ATTR_LABEL_TEXT, \"测试结果\");
三、设置垂直scroll,
SetCtrlAttribute (panelHandle, PANEL_TABLE, ATTR_SCROLL_BARS,
VAL_VERT_SCROLL_BAR);
四、当table满行时，显示最后插入的一行
//获取行数
GetNumTableRows (panel, PANEL_TABLE,&row );
SetCtrlAttribute (panel, PANEL_TABLE, ATTR_FIRST_VISIBLE_ROW, row);
其中，row为最后一行的行号，
五、写入数据
//设置这一行五列数据
SetTableCellVal (panel, PANEL_TABLE, MakePoint(1, row), \"传感器的温度值\");
SetTableCellVal (panel, PANEL_TABLE, MakePoint(2, row), data);
SetTableCellVal (panel, PANEL_TABLE, MakePoint(3, row), \"290~300\");
SetTableCellVal (panel, PANEL_TABLE, MakePoint(4, row), \"℃\");
SetTableCellVal (panel, PANEL_TABLE, MakePoint(5, row), state);
如果都是同一类型，可以用for循环写入：
for(i=1;i<6;i++)
SetTableCellVal (panel, PANEL_TABLE, MakePoint(i, row), “值”);
