The variable V[customers] is created as a table variable. For each row 1,2,3... the components

  V[customers.account.1]
  V[customers.name.1]
  V[customers.city]
  V[customers.country.1]

  V[customers.account.2]
  V[customers.name.2]
  ....

 can be used as individual variables.

• In contrast to normal variables, invalid component names, e.g. V[customers.xxx.1] cause a  syntax error message.
  
• For non-existing row numbers the following rules apply:
  Reading a table cell with a non-existing row number returns "". Writing into a table cell with a non-existing row number first creates the row with empty cells and then writes the value into the specified cell. It also creates all intermediate rows with empty cell values, for example rows 2 to 99 when you write into row 100 and only row 1 exists.
  
• The total number of rows is V[tabname.rowcount], the number of columns V[tabname.colcount]
  
• You may change the rowcount V[tabname.rowcount] directly with  Set. For example, when you intend to fill a table with many lines, it is quicker to first set the total row count and then to set all cell values.
  
• Column names can be read with the notation V[tabname.colname.k]  e.g. "&V[customers.colname.3]" is "city".
  
• With Clear V[tabname] all rows are removed and V[tabname.rowcount]is set to 0.
  
• You may use the notation  V[customers.cell.account.1] instead of  V[customers.account.1]. This is supported to assure compatibility with the table display using the Table command.
  
  
• All status variables V[tabname.stat. ...1] used in the table display with  Table keep their values. If necessary you can clear them explicitely with Clear V[tabname.stat*].
  
  
• The string representation "&V[tabname]" of a table variable generates a "JSON" format which is compatible with the  JavaScript object notation. Example
  
  Set V[customers.account.1] "1000"
  Set V[customers.name.1] "M&S Inc."
  Set V[customers.account.4] "2000"
  Set V[customers.name.4] "ABC Inc."
  
  For &V[customers] the following string is generated:
  [{"account": "1000", "name": "M&S Inc.", "city": "", "country": ""}, {"account": "", "name": "", "city": "", "country": ""}, {"account": "", "name": "", "city": "", "country": ""}, {"account": "2000", "name": "ABC Inc.", "city": "", "country": ""}]
  
• You can use the same JSON type notation in order to set a table variable value
  
  
• Since the normal GuiXT variables are limited to 4000 bytes, use GuiXT long text variables if you expect a large table. The commands are  CopText ...fromTable= ... -json and CopText ...toTable=... JSON
