How to fix an issue displaying data sets with numeric headers using widget TABLE (same for DATA TABLE)

Hi,
I need to display some data (initially read from an external file like csv, using Operations, data saved in the form of ArrayList in a pool variable type of java.lang.Object). In my data file first row - is the headers row, all the rest are just data to display in the table...
I'm using both widgets: TABLE **and **DATA TABLE. Now cases 1 and 2:

Case-1) There is NO problems when the data file has ordinary strings starting from letters ("what ever33", "header1", "FirstName" etc): all data rows displayed correctly, both widgets TABLE or DATA TABLE;

Case-2) When the data file has a headers starting from any digit (0..9, something like: "1", "2nd Name" etc ) - then there is a problems displaying the data in the TABLE widget:
- No data rows displayed, instead all rows are populated with the headers row repeatedly (see example);

widget TABLE properties:
- Headers:
- Content:
- Column keys:
(for DATA TABLE only) - Data source: Variable

Example of input data source:

col1,2,3, 4Start,-5,6x,col7
row1-col1-data,row1-col2-data,row1-col3-data,row1-col4-data,row1-col5-data,row1-col6-data,row1-col7-data
row2-col1-data,row2-col2-data,row2-col3-data,row2-col4-data,row2-col5-data,row2-col6-data,row2-col7-data
row3-col1-data,row3-col2-data,row3-col3-data,row3-col4-data,row3-col5-data,row3-col6-data,row3-col7-data
row4-col1-data,row4-col2-data,row4-col3-data,row4-col4-data,row4-col5-data,row4-col6-data,row4-col7-data
row5-col1-data,row5-col2-data,row5-col3-data,row5-col4-data,row5-col5-data,row5-col6-data,row5-col7-data

This is what we can see in the output table:

col1,2,3, 4Start,-5,6x,col7 
row1-col1-data  2   3   {{ $eval(column, row) | uiTranslate }}  -5  {{ $eval(column, row) | uiTranslate }}  row1-col7-data
row2-col1-data  2   3   {{ $eval(column, row) | uiTranslate }}  -5  {{ $eval(column, row) | uiTranslate }}  row2-col7-data
row3-col1-data  2   3   {{ $eval(column, row) | uiTranslate }}  -5  {{ $eval(column, row) | uiTranslate }}  row3-col7-data
row4-col1-data  2   3   {{ $eval(column, row) | uiTranslate }}  -5  {{ $eval(column, row) | uiTranslate }}  row4-col7-data
row5-col1-data  2   3   {{ $eval(column, row) | uiTranslate }}  -5  {{ $eval(column, row) | uiTranslate }}  row5-col7-data

Chrome console messages:
